The IESG can move a document to "Historic" status.  Generally, that's 
done by an RFC explaining why.  I don't know of any attempt to do that 
to 2228, and I probably would if one were pending.

That doesn't mean that anyone is or isn't using it -- there are many 
unused Proposed Standards.  Whether or not the IETF should undertake 
the consider effort necessary to clean these up is debatable.
