Yeah, that's pretty much what I said above.

I vote for highway=stop + compass=X on the way at the stop line plus
traffic_sign=stop + compass=X at the actual stop sign location.
Actually, I don't "vote" for anything.  The tag highway=stop is
already being used this way (sans compass=X), the tag
traffic_sign=stop is the obvious extension of traffic_sign=*, and
compass=X is unlikely to interfere with anyone else's tagging
(although if there is already a tag for this then I'll use that
instead).  The use of compass=X is obviously optional, but it gives a
way to be explicit in the normal case and gives a way to correct the
default in the exceptional case.  Without editor support it probably
won't be heavily used, but oh well.  In the meantime, if someone wants
to use the tag stop:direction=forward/backward, a bot could go through
the db periodically and fix that into compass=X (when there is only
one way, and the direction of the underlying way has not changed since
the tag was added).
