Sure. It's a fallback, not a feature. It'd just mean that 'my graphics

One thing that bothers me is that gnome-shell is doing
compositing/scaling that is not much more sophisticated than the
original MacOS X (which had software-only rendering) and yet it requires
a very good graphics driver. 
Do we have a very good fully open source drivers available?
 Those boxes had very slow processors by
today's standards, and yet they were perfectly usable.  Not blindingly
fast, but perfectly usable, with compositing and animations and such.
I remember I was able to run OSX (some say legal if you are a Mac developer) many years ago, in
a Pentium 4 2.8GHz HT(CPU) with only 128MB nvidia GPU. The usual effects you have in Mac computers
are the same, very smooth(only few artefacts) even without an nvidia driver installed.

I'm all for using graphics hardware as well and as thoroughly as we can.
But it bothers me that we may be able to do all that gnome-shell needs,
in software, and we are not pursuing that route yet.  Maybe someone
will :)
