HTTP/2 backend connections should be reused, however be aware that currently
there's one connection pool per thread, so chances are, if you have 2 frontend
connections, they ended up on 2 different threads, and so wouldn't reuse the
other connection. I'm not sure how you ran your test, but using "nbthread 1"
should make it reuse as you'd expect (or just having more frontend connections
than threads, at some point you should see some reuse).
