Well, it may have important a11y impact, in that a11y may need to do the
compositing (for magnification) instead of metacity (until/unless
metacity takes on the magnification service tasks).  For that reason,
it's potentially risky to either make it nonconfigurable, or even to
turn it on by default (and thus develop a 'dependency' on it).  Of
course we don't want magnifier users to be left behind when the other
cool compositing features land.

That said, I think the metacity team is aware of the a11y concerns and I
am optimistic that the end result will be very good for magnification as
well as everyone else.
