It should not denote both the site and the page. Rather, if one does
a GET on the site URI, one is (I propose) redirected to a default home page.

Right. So "http://"{AUTH}"/" denotes a site. And just because GET
might return a representation of e.g. "http://"{AUTH}"/index.html"
does not affect the denotation of the site URI.

Err... well, if it makes you happy, we'll call it a welcome
page (rather than the home page of the site ;-)  or let's just
say "web page", eh?

Well, not necessarily using the actual redirection machinery,
but it is a logical redirect, since the server is responding as
if some other URI was specified. I.e., you say http://example.com/
and the server behaves as if you said http://example.com/index.html.

I am proposing that a consistant, standardized
interpretation be introduced (or rather, made official)
whereby "http://"{AUTH} denotes a server, 
"http://"{AUTH}"/" denotes the root site of a server,
and a GET to either of those URIs results in a 
redirection (either actual or logical) to a default
web page for the root site of the server.

Such behavior would be consistent, and also inline with what
most servers already do, and having such an interpretation
gives us distinct URIs to talk about the server, the site,
and any resource in the domain of that site.

And having distinct URIs for those allows us to work with
descriptions of each of them without ambiguity.
