Not a good choice imo. According to a recent discussion, mappers might
want to use that tag specifically to map buildings built into bridges -
like these:

Bridges also have to be handled completely differently in code than
normal buildings for any remotely sophisticated rendering. So even if
you want to avoid bridge relations (which I don't necessarily agree
with, see my other mail), please choose a new, unambiguous key for the
bridge outlines.
