    Thanks for sharing.

    Key exchange is out of scope, but committee should at least provide guidelines/best-practice.

    For example, encourage key isolation (for a server implementation, it's maybe too convenient to use one key for all clients), key rotation&revocation.

    I suggest adding brief clarifying language that:

    - this specification is packet-format focused,

    - Sender Identifier does not mandate a single key-management model, and

    - future companion specs may define interoperable key exchange/onboarding without changing the encapsulation format.
