Should I switch to quictls 1.1.1 instead?
Possibly, yes
I did this, and now browsers do not switch to http3. A direct request
that forces http3 works, but browsers are not switching to it based on
the alt-svc header. Tried both firefox and chrome which have been
successful for me in the past.
I grabbed a sniffer trace of UDP/443 when I ask for the page in firefox.
Here is a wireshark view of that when following the UDP stream:

That certainly looks to me like a significant amount of two-way
communication, but as it's encrypted, I have no idea what it might mean.
The browser's console reports that the connection is http/2.
With quictls 3.0.7 it was working. I will try rebuilding and see
whether it still does. There was probably an update to haproxy as well
as changing quictls -- my build script pulls the latest from the 2.7 git
repo.
Output from haproxy -vv:
