HTTP/2 Zero-Day Vulnerability Results in Record-Breaking DDoS Attacks
I'm not an area expert, but common issues raised over the years:
- HTTP/2 as implemented by browsers requires HTTPS, and some people don't like HTTPS.
- HTTP/2 was "designed by a committee" and has: a lot of features and complexity; most of those features were never implemented by most of the servers/clients; most of those advanced features that were implemented were very naive or buggy [0]; some were implemented and then turned out to be more harmful than useful, and got dropped (HTTP/2 push in browsers [1]) etc.

HTTP/3: Everything you need to know about the next-generation web protocol
Just to add a few bits: I'm not an infra person so can't tell about managaing a H2 deployment, but from frontend web performance perspective H2 is very interesting and somehow not used to its full potential.
H2 has built-in support for interesting concepts like prioritization and re-prioritization of requests. Unfortunately, most impls in clients and servers are either not full or not very good:
I recommend googling "http/2 prioritization" and checking blogs and talks from Andy Davies and Pat Meenan. The subject is super interesting and hard; browsers need to make certain assumptions whether scripts, fonts or CSS are more important and should be prioritized and it's non-obvious how to handle its best
