Hello LAKE,
(hello CoRE: This effectively only updates the recipient list, please
reply to this rather than the original)

Thanks to Marco's pointer at the LAKE rechartering, I'm also posting
this to LAKE:

I've written up a proposed extension to EDHOC that should help ensure
that its extension points remain usable, based on similar work that has
been done for TLS.

Note that there is no need for constrained endpoints to do anything
about these -- my expectation is that their unconstrained peers would
have enough information to decide whether applying some GREASE is
practical for a given exchange, and that should suffice to keep the
network as a whole well lubricated.
