Changes to BIP-360 - Pay to Quantum Resistant Hash (P2QRH)

From my understanding the main reason of using version 3 is the fact that in order to re-use version 2 you need a different payload size, while your size is exactly 256 bits (hash), and it is better to use a newer version than extend it with some unneeded byte(s), consuming blockchain space forever.

I think there is a misunderstanding here. P2TR is version 1, and Ethan was discussing using either version 2 or version 3, having already decided not to use the same version as P2TR.
