Really?

way/800207987 is clearly not `layer=-1`...

osm.wiki/Frontage_road

> Do not use a `highway_link=*` tag for the frontage road. Simply use one of the normal `highway=*` tags.

Their other changesets seem fine, other than changeset/178131552 (double decker buses go on that road, but is tagged as `maxheight=3.5`?) and changeset/178132207 (mapillary seems to disagree?), I will take a deeper look later.

Slippery slope: if any road that branches away from `=*` can be considered a `=*_link`, then almost every road can be considered a link.

Would `=unclassified` work?

I doubt it's a `=primary_link`. It could be seen as a normal road, not a link/ramp of any kind.

Again, please use `route_ref=` instead of abusing `network=`.

1. Please don't use descriptive names. Use `route_ref=` node/13657534656 node/13657534642
2. Please don't attach bus stops to the road. That's `public_transport=stop_position`.

unmarked or informal?

I don't see what inspiration the quoted way can possibly give. That's clear square; this here at Kam Chun Court is a rectangle. I hope the difference is clear enough that I don't need to rigorously define what is square and what is not.

Is it not `covered=yes`?

Is it not `covered=yes`?

Don't know what you are doing drawing buildings that already exist
