I agree.

BTW, here are some more buggy line from lisp/gnus: (These are just a
small minority of the problematic lines as far as I can see from "grep
downcase -RHn lisp/gnus")

nndoc.el:511:   (intern (downcase (mail-header-strip encoding))))))
nndoc.el:905:   subtype (downcase (match-string 2 content-type))
rfc2047.el:674: (concat "=?" (downcase (symbol-name mime-charset))

Failing Cases:
(downcase "ISO-8859-1") ==> ıso-8859-1
(downcase "text/plain") ==> text-plaın
