Seem to be unused; did you previously do something interesting with be_no_ssl?
I feel curious about the fact you are not using nbproc, which kind of CPU is running this haproxy?
Thanks for sharing this configuration, it's highly illustrative.
Are you no longer using the source port exhaustion workaround discussed here[1]?
