Fun discovery: it's possible to detect multisampled edges very precisely just by checking if the depth samples are planar.
If you weigh the MSAA sample offsets, you can get directional sensitivity even.
I vaguely remember similar demoscene-experiments from the late 2000s adding AA to a GBuffer based on a multisampled depth pre-pass, but never saw any decent write up about it.
Anyone know of anything similar?

Dug it out of deep storage, it was Frameranger by CNCD/Fairlight. Some good old mecha-spider racecar robot action. https://directtovideo.wordpress.com/2009/11/13/deferred-rendering-in-frameranger/ Not directly applicable, but it's great to re-read these early deferred rendering challenges.
