It's not actually very hard to expose the depth information. It actually became easier over time due to all the stereo changes as well.
Main issues that will happen is that some games won't work with it (Too bad, you'll have to deal with it)
and that it may not work with stereo rendering, haven't checked.
I did a PoC quite a long time ago to see if it was viable, and it definitely is.
Here's a picture of Animal Crossing with only its depth information shown, had a minor bug with the depth information being offset, but it's a PoC for a reason.
