No, there are absolutely no chances for such a change.  Such changes 
have been tried and failed.  MIME people will never agree to change 
the default.

So many e-mail programs use the charset parameter to display MIME entities 
labelled as text/*.  If the charset parameter is absent, such programs will 
assume that the MIME entity is us-ascii.  This change will invaliate such 
programs.

Cheers,
