There is no security risk in allowing the Gimp to position its window
relative to each other.

You can see a half-hearted example of this on OS X. You can click the
dock icon of a running application to raise all its windows above
other applications but the z-order among the windows of the single
application is preserved.

This is completely possible regardless of allowing z-order changes.

AFAIK there is nothing stopping any application from creating several
windows per second which will automatically get on the top in z-order
and nothing stopping it from creating so large windows it will
effectively kill the compositor (either by means of OOM killer or by
means of swapping it out and having it run on swap.

The problem with multi-window applications is that multi-window UI is
not really well supported neither in Windows nor in X-windows so you
always get bad experience.
