Note that this representation is only for the way how signatures are signed, identified, and represented before inclusion in a block. For post-block-inclusion, there is EIP-6404.
The new signature scheme proposed here is close to what the “SSZ Union” approach in Vitalik’s notes / EIP-6404’s test section is referring to, so it doesn’t conflict with the approach based on “SSZ Union”.
For “SSZ Normalized” approach, the transaction’s mempool encoding is not linked to the post-block-inclusion encoding, so there is no concern either.
