First priority should be to obey POSIX (which GNU grep violates e.g. by making EREs the default even when given the -G flag). But concerning everything that goes beyond POSIX, GNU is a defacto standard.
In this case, there are already a lot of flags not required by POSIX, so 'we don't like non-standard options' can hardly be a valid objection. The only problem I could come up with is that it changes the previous meaning of the -H flag on OpenBSD (which was removed exactly because it was an OpenBSD-only flag). Concerning ports, I don't see how this could cause problems. Rather, any script that might use the -H flag should be fixed by this change as they will rely on GNU behaviour. However, I don't think there are any. But let Theo decide ... :)
