It would probably be better to go the other direction and break out
30.03 on those other workarounds so that they aren't incorrectly
applying to 30.02 as well.  We don't have any platforms using 30.02 at
the moment, but one could show up in the future and these workarounds
may or may not apply.

If we're sure a couple years down the road that no 30.02 is ever going
to materialize, we can come back and consolidate some of the entries to
help simplify.  But for now we should try to follow the workaround
database exactly and not make assumptions about versions that don't
exist yet.
