I think that's irregular tagging, and not likely to be interpreted the
way to intend by a number of routers, but I agree that this is a
reasonable interpretation for mkgmap of that tagging when it occurs,
which is the only thing that matters here.

I didn't mean there were always clear aisles.  Just that you can
usually/almost-always draw a way that goes into the area that more or
less represents what you can do.

The real issue is that the OSM tagging scheme is not rich enough to
capture these nuances, and thus different people have different
preferred ways to approximate reality given the tagging scheme that
exists.  Clearly a difference of opinion among reasonable people --
thanks for the discusision.
