Hi Adam,
Commenting on your question:

The general accepted practice (defined in BIP43) is to define a dedicated purpose field for each kind of key derivation and address encoding. There is a dedicated purpose for pre-SegWit, SegWit, multisigs — and now a purpose for Schnorr sigs/Taproot outputs is needed. That is why I brought forward this proposal, which addresses exactly this need - and also will support at the same time multisigs and pre-Taproot outputs, making all previously used purpose fields redundant, simplifying future wallets.
Kind regards,
Maxim
