That's true, I'm just not interested in maintaining it myself because I
think it's a bit silly regardless :). I have no problem at all with
someone maintaining a DKMS nvidia package or grsec-specific package to
have it work. It doesn't harm me in any way to have the choice available.

This is actually one of the few grsecurity features that tricked
upstream. It's available as the `hidepid=2` mount option for /proc.
Sadly it breaks systemd to some extent due to the cgroup filesystem in
the kernel being inadequate (no namespacing support).
