Why would the URI be more or less non-compressible than the Host: header ?

As I see it, we save a header field, and any compression or optimization based
on prefix matching will have an easier time with one field than with two
fields ?

And if you mean that the URI should not be compressed for performance reason,
in HTTP-routers, I would argue that the same holds, possibly even more so,
for the Host: header...

That would be in direct contravention of the standard:

   [2616, 5.2]:

   1. If Request-URI is an absoluteURI, the host is part of the
      Request-URI. Any Host header field value in the request MUST be
      ignored.
