I added a comment at the first bug about this issue, and I think we should continue the conversation there, so not to be stuck on this sidebar. https://github.com/openstreetmap-carto/openstreetmap-carto/issues/4438#issuecomment-4227549506

We're not allowed to use abbreviations or map for the renderer. (osm.wiki/Abbreviations). This issue has already been brought up as bugs; (https://github.com/openstreetmap-carto/openstreetmap-carto/issues/4438) (https://github.com/openstreetmap-carto/openstreetmap-carto/issues/1513)

I know that this may render the full I 80 Business in certain map styles, or not at all, but we aren't supposed to map for the renderer.

I planned to convert this to a cycleway tag on the main road, but forgot to implement it. It's fixed.

...and by "not private", I mean "private."

The Bay Trail ARCGIS said it's part of the trail. I removed the part where the trail west of the airport, but the area southwest of it has heatmap activity and there's no evidence that it is not private.
