I think “we all agree” is a prevailing assumption, but given my experience with HTTP Upgrade to TLS for CUPS I don’t think all hope is lost.

Instead of assuming that it won’t work because WebSockets failed, I am now trying to collect real information and do some testing to see what exactly doesn’t work and why.  If we can find a path that allows clients to upgrade successfully or detect when it won’t work then we will have both the reliability needed to deploy it AND the information needed to document the failure modes for the spec.
