Section 17.2.5.1

A server MAY send Retry packets in response to Initial and 0-RTT
packets. A server can either discard or buffer 0-RTT packets that it
receives. A server can send multiple Retry packets as it receives
Initial or 0-RTT packets. A server MUST NOT send more than one Retry
packet in response to a single UDP datagram.

When the server sends multiple Retry packets in such a scenario, do the
Source Connection ID fields need to be different (or the same) across
all of them? (Or does it not matter?)

Yes, a server might send many Retry packets. We don't require that the connection ID be the same though. Our defense there is that the client will only process one Retry.

This is a question and doesn't require any action.
