My only complaint is when breaking ABIs and not being clear about
doing so. Otherwise, it is up to platform maintainers to not upset
their users (including if some of those users are FreeBSD).

Then perhaps that part of the binding should be omitted for now. But I
don't see how if this works for FreeBSD how it wouldn't for Linux.
