No, I didn't mean that. This would probably bloat the GUI while beeing
a rather obscure feature. Just one global button "output Joined multichannel"
would be enough IMHO.
I just wanted to stress the point that you can mix different number of channels.
E.g. you choose "joined multichannel" and you can select several mono tracks,
a stereo bus and a 9 channel ambisonics bus (just to give an example) and
thus get all of your export in one single export job (some source tracks
as mono WAV, a conventional stereo mixdown to burn for a demo CD or for
mp3 encoding and the ambisonics master). If you would select split multichannel
then you would get the same tracks, but every track in a mono wav of its own
(implying some clever naming scheme and some "sanitizing" of file names)

seems to be a clever aproach, because you always get a sane configuration.

If JACK is blocked during a two-hours export job while I am sleeping,
I am just fine :)

Scriptability or some batch soultion have another implication, which
may not be immedately obivious: you can check the scripts into SVN.
(I for my part value this comfort and additional safety very much
and allways check in all my session files, even the whole automation
subdir and I often review changes with gnu meld.)
So, if you just back up your sounds-dir (and the SVN of course),
you can re-run identically every export later on if you wish.
