The draft refers to application/x-rar-compressed, application/x-gzip,
unknown/unknown, application/unknown, application/rss+xml, image/webp,
video/webm. They are all unregistered, and in case of the first two,
cannot be registered without changing BCP 13. Are those a problem as-
well?

I don't think there is anything special about fonts that would make
that a bad idea compared to other kinds of resources. There has been
some interest in this and there have been some efforts, for example,
<http://tools.ietf.org/html/draft-singer-font-mime-00>, but as far
as I am aware nobody has gone so far as to ask the IESG to actually
approve a font media type.

(I think it might be best for the Applications Area Working Group to
draw up a list of common data formats with unregistered media types
and make a bulk specification that contains the absolute minimum to
register them all. If it were to do so, throwing in a couple of font
types should be no problem.)
