Agree.

I don't think so.  I'm saying that Bullet #1 should require that the
host part of Request-URI be a valid host.  OTOH, maybe that's
over-specification.  It need not be a valid host, just something the
server finds acceptable.  Which would mean that the words you just
moved would have to be adjusted to be consistent.

Summary:  I'm glad you found the other problem, and I'm mushier about
whether I think Bullet #1 should be changed.  However, I think that
the words regarding the host in an absoluteURI (#1) and the host in Host
must agree (once and former #3).
