Do we need that functionality?

Don't think so, setting alpha bleeding / chroma keying is all we
need to have in the kernel.

You don't need kernel support for this.  The fb apps (unlike X11 apps)
have direct access to the framebuffer memory.  They can simply fill some
screen area with the chroma key color.  I can't see any need for passing
around clip lists.
