as said before, the global useflag description should be updated (GRP
is long dead...)

Good for you since there is no issue :)

the *why* is not the purpose of a useflag imho: you cant link to openssl
from a gpl binary because its a 4 clauses bsd license; i dont remember
on top of my head but other constraints also have different reasons;
being "license incompatible" as the answer to the *why* is the best you
can do there.
