That is pretty much my take away on it as well.

However:

It could theoretically be useful in some kind of psychological horror game where you actually just want the player to feel like an actual schizophrenic or person in a drug fueled psychosis, whose reality is fundamentally unstable and filled with inexplicable, sometimes subtle, sometimes massive, discontinuities.

Instead of jump scares and spoooky scary ambience...!, just here, put the player through the fever dream hallucinator, now they're gonna have a whole different flavor of a bad time, hahah!

EDIT: Another funny way you can do mindfuckery in Doom is to set pi to be exactly 3.

This subtly but eventually infuriatingly warps the 3D rendering uh, paradigm of the world, of perspective itself, with sort of similar just... weird fucking nonsense going on.
