Multisig wallet transfer, security implications of signer giving their phrase to someone else

Normally, giving out a phrase to recreate your wallet is a bad idea.

If I have a multisig wallet – lets say 2 of 3 – and don’t want to participate as a signer anymore, I think I can give the phrase to recreate my wallet to someone else.

Even if we would both be in possession of that phrase – assuming there is no way to trustlessly do this – it seems that moving funds would still require the other signers in the p2SH script.

The only possible downside is if I retained access to the wallet and rejected signing transactions, that the new owner of my key would have accepted.

What are your thoughts? Am I missing something
