HTTP/2 Concurrent streams question

This is the right place to ask! It was implemented that way because RFC 7540
Clients SHOULD NOT open more than one HTTP/2 connection to a given
host and port pair, where the host is derived from a URI, a selected
alternative service [ALT-SVC <https://tools.ietf.org/html/rfc7540#ref-ALT-SVC>], or a configured proxy.
One workaround would be to create a second HttpClient in that situation.
As a matter of interest, what limit is imposed by the server in this case?
