Re: Re-chartering for extension work

[David Schinazi <[e-mail]>]

In general, I'm very supportive of rechartering to allow these new
extensions.

I'd prefer to have the charter just allow all extensions, and then use the
WG call for adoption consensus process to decide whether extensions are
in-scope at a given moment in time or not. But if the chairs/ADs think that
is too broad I can live with only opening up for specific topics.

One important problem though, is in the DATAGRAM case, the topic of flow
identifiers. Earlier, draft-pauly-quic-datagram-03 contained flow
identifiers. Based on community feedback, the authors removed them from
-04, and moved them to a separate draft-schinazi-quic-h3-datagram. I'll
admit that draft-schinazi-quic-h3-datagram is still very immature, but with
the new charter, I want to make sure we don't end up in a state where we
can discuss draft-pauly-quic-datagram but
not draft-schinazi-quic-h3-datagram. Some folks feel strongly that flow
identifiers should exist, and if we tell them that they're not in scope of
the WG they might be sad.

Because of this, I think the new charter should discuss topics as opposed
to specific draft names (which is what I assume Mark meant by [ adopted
extensions ] )
