Sure, it's easy to do. But the application that's using
it has broken source, and nobody will know until after it's
recompiled.
I'd just have a single flag for all, on the assumption that
they're either using old API exclusively, or new. But, again,
it leaves a land mine for the source bug in the application
that you're allowing to still work.
