It breaks P2PK and P2TR immediately. You are right that it also breaks addresses that have been re-used, since the pubkey has been revealed.

A quantum computer that can break ECDSA "immediately" is science fiction. Even when we have working quantum computers we'd probably still have decades or centuries before they can perform the necessary attack in the required time. It will be trivial to upgrade bitcoin when necessary.

when an attack becomes feasible, those address types are already compromised, so they will immediately become vulnerable
you are debating when an attack will become feasible, which is fine
I don't know about centuries, or it will be trivial to upgrade, lol
