Fom the know-how of the participants, i think so. For example the
core issue i am interested in, how to build and later standardize
more extensible reuseable forwarding plane packet headers through
programmable forwarding planes, that i something where AFAIK a
good amount of participants in vendors working with HW development
got insight.  Likewise now also more and more reserchers building
P4 prototypes of recent IETF protocols.  And learning limitation of P4.

That of course is just my favourite pet sub-topic. When it comes
to the evolution of "Internet" as global inter-AS paths to
metropolitan network connecting edge-clouds with subscribers
that are as varied as 5/6G towers, IoT devices and humans, i
think we also have a lot of experience.

And so on.

What we do not have is i think a strategy to coalesce discussions
about this. Eg: the gap between IRTF and IETF if you ask me.
