Exactly. And this also brings the following question:
How do you expect gnustep to be usable with _any_ window manager out
there (at least partially)? Or it would only work with exactly one
highly adapted specifically written one?
The idea that we will only run a pure gnustep environment with only
gnustep apps is far from the true. There are plenty non-gnustep apps
that users won't throw away, and also developing their equivalent
gnsutep variants can take years. Even if there are equivalent gnustep
apps still the user may choose to use the others base on personal
reasons, habits and tastes.
And don't forget other apps also evolve while gnustep evolves. gnustep
have a lot of work to do to reach them from behind (to be able to
provide features that they already provide) and that means more time and
developers that it has, because other apps also don't just stand and
wait.
Just look at wine: they're always steps behind of the real thing. Same
with gimp versus photoshop. And they have enough developers.
So I don't think that a pure gnustep, providing all imaginable apps is a
reasonable idea and people will always use other apps to.

I'm not sure if that would be the best way. It will work, but in my
opinion the problem gnustep has now is that is uses too many layers of
abstraction up to the real hardware. This makes it to be too slow.
Just compare how the old NeXT system run on a @25MHz machine, and how
does gnustep run on modern address@hidden machines.
