Hi Andreas.

I am kind of a detail mapper (mapping sidewalks as own ways and so on), 
but I am not sure about indoor mapping in general.

All OSM editor programs I know are not well fitting into the area of 
editing more than one level/layer: bridges are okay as nodes are not on 
the same location most often, but more is difficult.
If you ever tried to map a stairway from basement to the first floor (or 
above) of a building, winding around in between, you will probably know 
what I mean.

Mapping rooms is similar: Often Walls are exactly on top of each other 
(as they carry the building's structure and roof).

You see: mapping rooms is not trivial in general, but IMHO the problem 
is even bigger, if one already mapped the rooms of a building, while 
another one wants to fix e.g. the shape of the building itself (this may 
happen often).
What to do now with the rooms?
Of course that's a problem we always have when editing other's work; but 
here it's really much data that has to be corrected, and it's difficult 
to do so.

Room entrances of course are only useful in combination with rooms - so 
that's my answer to your question.

I would appreciate additions to JOSM (and other editors) helping to deal 
with problems like this: multiple levels, the always discussed problem 
of parallel osm-ways describing a road and so on.
If there would exist software support, I can imagine useful additional 
mapping, yes.
