What he said.
I'll add that proper use of HTTP v2 still involves sending an OPTIONS
request to the server, allowing it to respond with the configured values of
the various stub URLs, and then using those stubs to build out full URLs.
Clients may not assume that every server uses the same format for the stub
URLs, especially as that format is trivially tweakable using mod_dav_svn's
SVNSpecialURI directive.
