The same happened when TLS 1.3Bwasnarpundnthe corner. Several draft version with different implementations that browsers shipped before the RFC was finalized. OpenSSL wasn't as late as QUIC to implement TLS 1.3 though.

These are selective improvements, and where every millisecond counts, I don't think see anything negative about implementations want to get ahead of the game.

I think Caddy browser gained a significant market share because it supports HTTP/3 by default, while Apache (that uses OpenSSL) lags behind.
