Why not. I didn't look at the code (and don't know enough myself too) to
know if it is reliable but I may merge a seperated well-tested patch for
this case.

Couldn't it be more user oriented without needs to touch .offlineimap.py
at all? The main defect I see of the current implementation is that it
would affect all repositories.

I was thinking to something like :

  # [Repository Blah]
  # extraflags = [('gnus-expire','E'),
  #               ('gnus-dormant', 'Q'),
  #               ('gnus-save', 'V'),
  #               ('gnus-forward', 'W')]
