Yes. As we get close to EOL on 12, more and more things will not be MFC'd
and it will be safer to re-evaluate this then.... However, some care is
needed to ensure we can MFC it to stable/13 at the same time to avoid the
issues with big commits and needing to partially merge them and/or cope
with the merge conflicts. 90% of the removal will be a drop in MFC, it's
the last 10% someone will need to spend at least a little time
contemplating.
