I strongly support adoption. We don't want to end up with a gap in client
priority due to the h3 transition so timeliness matters. The broad input it
has already received makes it the right candidate for the WG to begin work
on - the core tension around e2e vs hop-2-hop is one we have in a number of
places and is something we might just have to focus on how we can put as
much of it into upgradable pieces that we can replace later. In any event,
that's something for the WG to deal with after adoption.
