Is there any way I can implement HTTP/3 in Apache?

Edit:

The QUIC protocol has now been made an RFC, see RFC 9000. Waiting for HTTP/3...

OpenSSL said somewhere that they will begin working on QUIC after they release OpenSSL 3.0. Not sure when OpenSSL 3.0 is going to be released.

Until that, maybe we can integrate BoringSSL into Apache, and start testing stuff with QUIC.
