On a per-posting basis? Probably not.

No.

(RFC 2047-enabled newsreaders exist today and can handle -- i.e. display
the characters displayable on the current terminal -- multiple charsets.
Newsreaders that automatically detect UTF-8 and a leagacy encoding may
exist, too. But these are not those newsreaders for which you claim UTF-
8 has advantages -- these newsreaders don't understand RFC 2047 nor can
they detect different charsets.)

Please note that this has nothing to do with the encoding of the
Newsgroups header. Sending raw UTF-8 in text fields has no advantages
over RFC 2047 but it does not create severe compatibility problems as
UTF-8 in Newsgroups headers does.
