This is an experimental revision in which I am trying to use Phabricator to
review a patch created by Claude Code.

Comment 3

[Philipp Hancke [:fippo]]

note: putting extmap-allow-mixed in the SDP suggesting that mixing one and two byte extension is allowed and then not supporting two byte is a bit weird. Also this should be nominated for interop2026?

Comment 4

[Harald Alvestrand]

note: Chromium is likely to send two-byte header extensions in more cases going forward - we have more than 14 extensions that we may want to use (so far, the set of default enabled extensions is less than 15, but it could flip any day).
