You are insisting on mapping features THAT DO NOT EXIST IN THE REAL WORLD. That is outright wrong for OSM and is not allowed.
In this changeset you created many railroad tracks that DO NOT EXIST at all! They might have existed in the past, but not anymore. There are no traces left of them whatsoever! Yet you insist that some form of combination of tags somehow makes it acceptable to have NON-EXISTING features on the map. No!
Tags are intended describe map features from the real world. These tracks DO NOT EXIST and no combination of tags will make them appear in the real world or satellite imagery.

Hello.
Could you please elaborate what are you editing here? "updated tags" is not really descriptive comment

Ok, why don't we map every single building that has ever existed during humanity's existence and just tag them as abandoned/razed. That sure will make the map very useful. 🙄🤦
If you want map features from the past, that's what OHM is for. Not OSM
I haven't answered your "main" question because "it is used very usefully" is not a proper English phrase and I have no idea what you mean and what you are asking.

Drawing railways which DO NOT EXIST is incorrect information and tagging for renderer. They might have existed in the past, but not any more. OSM is about the way the world is NOW, not in the past. If all traces of that rail is gone and doesn't exist in the real world, it doesn't belong on OSM.

Hello.
Do you know the name of this bar?

As documented in osm.wiki/Names#Names_are_not_for_descriptions the name tag should not be used as a description.
Additionally, looking at man_made=water_works "man_made=water_works" doesn't seem like an appropriate tag for this situation.
manhole=* sounds like a better match.

You are doing great job figuring things out. 👍🙂

If you have Android phone, you could also install StreetComplete or Every Door apps to help fill in missing details while on-the-go. There's also Vespucci, which is more like iD for Android.

iOS also has Every Door and Go Map!! is like iD.
Using these apps right on the spot might be easier than trying to remember what you saw out there and go home to map later. 🙂

If you know other details like address, phone number, biz hours, website for this place, that would be useful. 👍

Rather than deleting and re-drawing, it's generally best to modify/update existing feature. This way you are preserving history of that object if there's ever need to reference back to it. 👍

These trees are already mapped as separate nodes. Mapping them also as a tree row way would be double-mapping and go against osm.wiki/One_feature,_one_OSM_element

Should this be a park or perhaps place=square be more appropriate here? place=square
Or "highway=pedestrian" + "area=yes" highway=pedestrian

You tagged both of these ways as having 8 lanes each(16 lanes total). On satellite imagery I counted 10 lanes. Map renderers that support displaying lanes will have this area showing a total mess. So either each lane needs to be mapped as a separate way or there should be only 1 way with the correct number for "lanes=" tag.

"url=" is an ambiguous tag with various meanings. Perhaps you meant "website=" tag? If so, then it's intended for official websites, not news paper articles.. I'll update it to https://www.zaqart.com/projects/reclining_liberty/reclining_liberty.html since that is the artist's website. 👍

And no, not 3. All the ways that I listed above are either partially or completely DO NOT EXIST in the real world and do not belong in OSM

3 out of 30 that I looked at, out of 126 ways your changeset affected. 10% error rate in unacceptable in OSM.

Having non-existing features in OSM purely so that you can have them in ORM is "tagging for a renderer" and that's wrong.
If you continue to insist to have non-existing features which have been COMPLETELY removed with other infrastructure built in that place, not built over it, but INSTEAD of it, this will be raised with DWG because you are creating an invalid data model with features that do no represent the real world.

I wonder what's bigger vandalism and creates more damage to the map, removing disused and completely non-existing features or or creating fake features in the name of restoring deleted disused ones.🙄
Just a few imaginary tracks that I found spending 5 minutes looking only at one corner of your changeset. I'm sure there are many many more that must be deleted because they don't exist.
