Chicken & Egg or Egg & Chicken.  Someone has to start.
Until there is evidence that list headers are being used, MUA authors 
will not in general support them... and currently the only MUA I know 
of that does use them is exmh (and that has a couple of wrinkles I 
could do without).

We probably also ought to use the List-* headers as part of the loop 
detection... and long term deprecate the X-beenthere - however judging 
by the number of mailman 1.x installs around and the amount of people 
with procmail filtering on that its likely to be a painful process.

We do need to document the use of the headers and potentially have a 
means for disabling them... however I would very strongly suggest that 
this is not made easy - ie not a web config item, and if we do use 
List-* as part of the loop detection remember that people using it may 
screw themselves royally.  If its a configurable my tendancy would be 
to put it in mm_cfg.py and ideally reset it on each upgrade.

BTW for people wishing to strip these then it may be better to do this 
in MTA filtering - exim can handle this easily.

I am strongly resisting the temptation to comment on the buns thread.
