Good to know, thanks for clarifying. I hadn't dug that deeply into it.
You're correct, though, that there are other reasons not to add it to
DRM. There's no standard way of connecting this display to your
computer, and there would be cause for users to want to do it
differently if an attempt at standardization was made. That's probably a
solvable problem, but would require extending DRM in ways that aren't
really worth the trouble imo. It'd be cool, though.
