Maybe I'm missing something, but wouldn't this turn into a hard fork the
moment you try to spend an output created in one of these extension blocks?
So sure, the block that contains the extension would be considered valid,
but unupgraded validators will not update the UTXO set accordingly, meaning
that those new TXOs can't be spent because, according to their rules, they
don't exist.
