What the clause requires
Keep using the address you are already talking to. §9.6 says a client "SHOULD ignore packets received from a server address other than the one it is currently using for sending packets" — a SHOULD, so quietly discarding them and objecting are both conformant. Following the new address is not: nothing is listening there, and a server may only move a client to an address it advertised as its preferred one.
Judged against RFC 9000.
