I see what you mean, have the P2P messages depend on whether the peer
is running old code (doesn't know about tail emission) or new code
(does know about it).
I don't think this can work in this case. It worked for Segwit because
the P2P differences involved only signatures (which determine whether
the transaction is valid), not the *effect* of the transaction, that is,
how it changes the UTXO set. Consensus requires all nodes to always
agree on the UTXO set.
