thanks for that reminder link.

what missing (besides work estimates ;-) is mention of how all that
might affect the current UI, and the current list of MH facilities.
i'm sure you're hoping most of it can be done "under the covers", and
much of it can, but i we should also be thinking of the visible parts
(as with lyndon's lua explorations).

show's invocation of mhl is an example of this.  isn't the whole
notion of "showproc" vs.  "showmimeproc" a bit artificial these days? 
if there were an entry (similar to) this in mhn.defaults, then
couldn't a bunch of code in show.c just go away?
    mhshow-show-text/plain: mhl %F
(i haven't tried this, because i have on need for mhl on body parts, but
it seems like something like that should work.)

to make a change like that would affect a lot of documentation, and
might affect a lot of people's configs.  but it might also clean up
the overall architecture appreciably.
