yEnc-encoded articles in newsgroups

Hi all,
I've noticed yEnc-encoded articles in some newsgroups of the Big-Eight (have a look at soc.culture.french for instance).  Examples:
   <17ba4ef578674e9c$60891$141478$64d91c8e@news.vipernews.com>
   <1O6IN.329500$7uxe.279980@fx09.ams1>
Wouldn't it be worthwhile having NoCeM notices of type "binary" or like to help cleaning non-binary newsgroups from these unwanted articles?
Naturally, other kinds of "binary" stuff could also be in these notices, and not only yEnc.
Just asking, in case a current NoCeM issuer would be interested in adding such filters.  (I'm not going to send NoCeM notices.)
