Yes. Here is an excerpt from the registry:

#The value space for MIBenum values has been divided into three
#regions. The first region (3-999) consists of coded character sets
#that have been standardized by some standard setting organization.
#This region is intended for standards that do not have subset
#implementations. The second region (1000-1999) is for the Unicode and
#ISO/IEC 10646 coded character sets together with a specification of a
#(set of) sub-repetoires that may occur.  The third region (>1999) is
#intended for vendor specific coded character sets.
#...
#Name: ANSI_X3.4-1968                                   [RFC1345,KXS2]

Do we really need the "q" in the Accept-Charset case? What does it mean?
(Especially since we don't want to expose any UI to the user for
Accept-Charset.)

I don't like the tone of this. I've known you personally for a (little)
while, and I doubt that you intended it to come across this way.
