Thank you for the draft. I was wondering if this should be a QUIC frame
instead of a transport parameter.

A frame would make this more interesting for the more general case where
the set of addresses of a node is not static. Take for example a QUIC
connection between two mobile devices (where interfaces / path can come up
/ go down), or for servers located behind NATs / firewalls (which might
need some time to discover their public addresses).
