I've just re-checked: while it's still possible that this may happen,
guaranteeing
that there's no negative impact will take lots of work, so progress may be slow
or the change never happen at all.  Besides, even if this would happen, we
probably cannot just drop support for Solaris 11.4 versions before such a
change.
