03:31 < theStack> would a potential change to x-only ECDH for BIP352 even work, considering that the A in the SP context is not an x-only pubkey, i.e. doesn't necessarily have even y parity? can each side pass in the x part of the other side's plain pubkey and it just works(tm)?

03:44 < theStack> ah nvm, seems that it does: https://github.com/bitcoin-core/secp256k1/pull/1198#issuecomment-1878766653
04:33 < sipa> theStack: imagine the function e(aG,bG) = abG (which we cannot implement, but is well defined
04:33 < sipa> then x(e(A,B)) only depends on x(A) and x(B)
05:04 < theStack> sipa: makes sense, thanks!
