In a multi sig setup, is a part psbt ok cryptographically to send in the open? Since it it 'signed' already?

For instance send a psbt over text, nostr, etc .. or is that a big no no?

If you have a partially signed transaction you need to send to another signer, and you do so by an unencrypted means over clearnet, then the UTXOs involved in that transaction can be provably linked to you.

No one will be able to access those funds as a result of the blunder, but they may have an idea of who to $5 wrench attack.

Gotcha.

I was not thinking privacy, rather actual loss of funds and security.
