+1 x DNS SRV

but I think it would be great to generalise its usage to discover if a domain support HTTP/1.1 or HTTP/2 or both
independently if they run on different ports or on the same port.

> HTTP2 is carried over TCP. So when HTTP1 and HTTP2 are not carried on the same TCP port, browsers need a mechanism to discover this port. DNS SRV provides such a mechanism and is already standardized. So I propose to add this discovery mechanism in a new section in section 3.
