My aim has always been the minimum set of profiles that will meet
real-world needs. Latest-version seems to be fine for that. The only
possible issue is interfaces that have been removed, but code that's
old enough to still be using interfaces that were marked obsolescent
11 years ago and removed 4 years ago probably needs _GNU_SOURCE or
similar anyway..
