HTTP2 always seemed like a great idea for the backend and a "meh" idea for the front end. On backend systems where networks and lines are mostly reliable and fast, HOLB is generally not a problem.

It's only when you start talking about connections outside a backend network that HTTP2's weaknesses start to show (specifically mobile networks).

I wouldn’t call it “meh”. For almost all sites, it’s at least a slight win for the significant majority of users; for most sites, it’s a moderately significant improvement for most users; for some sites, it’s a huge improvement for most users. Certainly high-latency, high-loss networks undermine its benefits, but it’s still generally a definite improvement over HTTP/1.1.
