Hi @ezbik, Requests notes it only supports http/1.1 throughout our documentation.

Any issues with other libraries trying to add QUIC or h2 support on top of Requests will need to be triaged there. We do not support this functionality.

[ezbik]

@nateprewitt then the documentation (proxies section) should be updated to prevent the users even trying to use http2 or http3 through the proxies..

[nateprewitt]

Can you point to what in our documentation suggested we'd be able to support new protocols specifically over SOCKS that we don't support otherwise?
