I agree with James. Having the spec define behavior that is never used by
any Web feature is very confusing.

Section 4 is not really needed at all since the HTML5 canvas spec defines
the canvas compositing behavior. If you want the Compositing and Blending
spec to define new compositing modes for canvas, then define a list of
operators that the HTML canvas spec can refer to, but don't define
globalCompositeOperation here. Don't even mention canvas here.

Another very important reason is also that if this property/behavior is

Describing something in a W3C spec that is not actually used by any
features in that spec, just so we can get the patent policy to apply to it,
borders on bad faith.
