Precedence: list

I must badly explain my point (or just wondering things that do not
exist finally), the question is indeed whether nodes will relay non
usual transactions or not and how to know what they will accept or not:

- my modified multisig 2 of 3: I did put OP_2 out of the usual redeem
script, the redeem script still matches scriptpubkey and scriptsig will
execute succesfully, that's a normal legacy P2SH or segwit P2WSH

- bch segwit recovery: it's a p2sh transaction without any signature
verification, as far as I remember there was a story that it could not
propagate in the network (even taking the risk to be stolen) and that
people had to contact a (honest) miner

- sha bounties: same as above, p2sh transactions without signatures

etc

Will all of those transactions propagate normally? And then the rule is
just that it matches the P2PKH, P2WPKH, P2SH, or P2WSH templates
whatever scripts you put inside?
