If you turn off the GPU, you'd better have the X server involved, if you
want the GPU turned back on again....  You certainly won't like what
will happen if X tries to touch a GPU that has been powered down.

And I'm not comfortable with a situation if an external process screws
up that you end up with an unusable system.

Similarly for enabling/disabling video outputs.  Again, you can end up
with a dead screen.

So the X sever better be involved at some level.
