They're physically monolithic features - technically, each object is a wall with a relief on it :)
It's not entirely accurate to tag it on the outlines - better would be individual line for each, as some are parallel next to each other, with width... but that's WAY into the OCD territory =) .
Tagged as walls, at least for now.

Name/desc - I tend to turn a blind eye on some names being a bit more descriptions, if there's no official name, and it makes data notably more usable.
Haven't noticed anything here ;)

The current status satisfies my desire for the balance of detail and data usability, no further changes from my side.
