In that case, I propose the following:

- I scrap the Taproot/Schorr and the two extensions inside the BIP, which will leave it with only parts and formats which have already been standardized (effectively, the legacy and segwit addresses).

Because here's the thing: The reason why wallets are not implementing sign/verify correctly is because there is no reference manual for doing so. This informational BIP is supposed to solve that problem by providing only a list of instructions for computing ECSDA sign/verify correctly.

Also, it is not visible right now, but there will also be a reference implementation so that wallet developers can actually code them correctly, as you've stated.
