A discussion thread was created here because EIPs now require EIP discussions to occur on Fellowship of Ethereum Magicians and EIP pull requests no longer work without a discussion link that points here.
Like Yamen wrote ERC725 X and Y is not a account standard, but could be used as such, as we do in LSP0-ERC725Account. LSP6-KeyManager is more comparable to ERC 4337, but it doesnt require any protocol changes. ERC 4337 can also be used in conjunction with LSP6 and LSP0 to make the account abstraction memory pool based, rather the pure transaction relay services. But this would require adding a function into LSP6 to support that (which is fairly easy todo)
