That's a good point.  Perhaps it would make more sense to have an exit_ref
tag (and document it on the wiki?).

It does, but I don't see any better relation for it, and I don't feel
comfortable enough with OpenStreetMap yet to want to start proposing new
relations.  What started me on this topic was one person on IRC saying
that they'd used the destination_sign relation for exits before, so at
least there's precedent.
