shop=* may be vertex in line without being tagging error
https://www.openstreetmap.org/edit?editor=id&way=688919381#map=23/38.19946/-85.74310
at first glance, this looks like a mapping mistake to me: shouldn't the way/688919381 (currently named Ticket Office) get the shop=ticket tag and the individual counters / ticket windows be just mapped as indoor=* features?
https://wiki.openstreetmap.org/w/index.php?title=Talk:Tag:entrance%3Dshop&curid=285297&diff=2411037&oldid=2338660 mentions another case, with highway=corridor connecting POI node and entrance node
If this is acceptable, then it would be not just shops but also offices and various amenities too, right? Is there a list somewhere of the things inside a building that can be connected to a corridor?
I think the intent of this validation rule was to dissuade people from mapping the shop as a vertex of a building or landuse area.

Maybe? So far I have seen it only for shops. And fairly rare, in cases where multiple levels, inconsistent level codes and overall complexity makes hard to guess where given shop has an entrance.

That makes sense and I guess that more custom one allowing only being vertex on pedestrian ways in theory can be created.

Relevant section of my diary entry that I wrote four years ago: https://www.openstreetmap.org/user/Anton%20Khorev/diary/45247#poi-1
It's in Russian, but you can start by looking at this image: https://antonkhorev.github.io/osm/diary/6/i/poi-levels.png
There's no way you'd be able to tell which entrance corresponds to which shop without connecting them.
This "point" vs "vertex" distinction can create other problems. Here's a video of someone trying to draw a path to an area by first adding a gate it passes through: https://youtu.be/DC9t99fOcrI?t=240 . It's impossible to do this because a "gate" is a "vertex", not a "point".
