That is great!
I think that further discussion in this mailing list about the justification
of the default for the charset parameter is not very useful. The discussion
should be moved to the ietf-xml-mime mailing list.
The current specification is a result of loooooong discussion. Nobody
is completely happy with it, but nobody is completely unhappy with it
(rememember that application/xml is also available). In their review
report of XML, the W3C I18N WG asked the XML CG not to change the precedence
rule of the charset parameter. If I create an I-D ignoring this request, I
would be ignoring the I18N WG as welll as strong oppositions from HTTP
people.
Since I intend to move the discussion to the IETF-xml-mime mailing list,
I merely state some facts here.

RFC 2376 quite carefully mentions both HTTP and real MIME.

IETF I18N guideline documents (RFC 2277 and RFC2130) recommend UTF-8 as the
default. When the WWW was invented, 8559-1 was the default. US-ASCII is
the intersection of the two.

I agree that this is misleading. It only talks about the case that
MIME headers are not available (I will send out a request for clarification).

Yes.
