The sad reality is that, in my experience, client support for using Alt-Svc
like this is pretty bad. The last time I checked, even Chrome can't handle
host redirection for HTTP/1.1 or HTTP/2 connections (I can dig out the bug
if you like).

For non-browser clients, which Ori's document is likely targeting, I'd be
shocked if they had any support for Alt-Svc in a fully compliant way. Given
that there is trouble implementing redirects ;-).

Firefox is the only one that seems to do Alt-Svc to its full extent
(protocol support aside).
