If many people are currently using clients that send Full Requests but
can't parse the charset parameter, then getting the servers to simply
add the charset will cause problems for all those people.

Hey, why don't you try an experiment?  You can get your hands on the
server that has the Unicode documents (www.unicode.org), right?  Change
that server so that it adds "charset=us-ascii" or "charset=iso-8859-1"
to the content-type line, and then wait and see how many people (if any)
