Chromium intends to ship the ALPS + ACCEPT_CH HTTP/2 and HTTP/3 frames
portions of the Client Hints reliability proposal, and we would like to
solicit WebKit's position.
As mentioned in the linked thread, the Client Hint Reliability proposal
is a set of features aimed at making Client Hints more reliably
available and mitigating mis-matches between a site's preferences and
the preferences stored in the browser.
In particular, The ACCEPT_CH HTTP/2 and HTTP/3 frames, combined with the
TLS ALPS extension, are a connection-level optimization to deliver the
server’s Client Hint preferences in time for the first HTTP request.
