Yes, or just respond with an error (always an option).

No.  It isn't the proxy's responsibility.

That is an implementation issue on the client side.  Yes, it is the
only implementation that make sense, but it is independent of HTTP
in the same way that DNS is independent of HTTP.

>The 1.1 spec should require complete names,

No. The 1.1 spec should not require that a client never do something
which does work under some circumstances, just because it doesn't work
in all circumstances.  If the client requests on an ambiguous URL,
it will get an ambiguous response behavior, which is as it should be.

In any case, this is a question of how to interpret the DNS hostname
within an "http" URL, and applies equally to any URL scheme that uses DNS.
