kazuho commented on this pull request.

+When the client finishes migrating to the preferred address, it retires the
+connection ID that was used for the original path ({{retiring-cids}}).
+Similarly, a client that continues using the original server address SHOULD
+retire the connection ID provided by the preferred_address transport parameter.
+Retirement of either of these connection IDs notifies the server of the
+address the client has chosen.

Yeah though not a "MUST NOT", that is already stated in the previous paragraph. That said, I think it would be better to merge the two paragraphs, as having two paragraphs describing what a client should do went migration succeeds (or fails) is confusing.

PTAL at commit f268ac4.
