You hit it on the money. It isn't critical to have multiple editions to
fulfill the objectives of the distribution. Its that simple. Anything else is
just eating away at resources that don't exist.
It's not wrong to work on this. I'd just rather not see it eat into resources
that are already being cut back. If Trisquel got to a point where the user
count increased significantly (it worked for more people) there would be more
money and more developers working on the project that could do things like a
KDE edition.
I don't see such editions doing anything more than holding Trisquel back from
having more users finding it possible for themselves to adopt it.
