Nice overview! There is a draft [1] that would support Alt-Svc in DNS. Lots to consider there but it is being presented to IETF. [1] - https://tools.ietf.org/html/draft-nygren-dnsop-svcb-httpssvc...

We use HTTP Alternative Services (RFC 7838). This appears as a Alt-Svc response header that advertises the availability of HTTP/3 to a client. The client uses its local knowledge (and maybe other heuristics) to decide if it wants to ch

This depends on how the proxy is configured to behave. One common pattern is to have a protocol terminating proxy talk to the client. Other component(s) sit behind this and they could be other parts of the system, tiers of caches or tiers

There is still a place for WebSockets in HTTP/2. The fairly recent RFC 8441 defines a mechanism to reserve a single HTTP/2 stream for bidirectional WebSockets. It is feasible for a similar mechanism for also work for HTTP/3,

Do you mean forward proxies? The HTTP/3 draft currently specifies how the CONNECT method is used. At present, it only allows you to create an onward TCP connection. So you have a QUIC connection between client and proxy, and a TCP conn
