Why is everyone so slow to move to http3?
because its over QUIC, which is different enough to be a pain.
Not that there is anything wrong with QUIC, at least its built by someone who knows what they are doing, unlike HTTP2
Why would you assume that we have to move from techX to techX+1? If I release http4 would you assume that you have to migrate to http4 at some point?
HTTPX2 isn't about the protocol version, it's the name of a python library to make http requests.
But yes, it doesn't support HTTP3. Here's the related issue: https://github.com/pydantic/httpx2/issues/92
