I'd agree with Stephen's comment:

This seems like a serious abuse of the FROM option, not to mention being
fundamentally unsafe --- the whole problem with FROM is that you can't
be entirely sure what the starting state is. So unless you can make a
pretty strong case as to why you need to do it like that, and that there's
no other way to handle it in the many months before v13 ships, I'm not
going to have a lot of sympathy.
