More choices and power for corpses cleaning skills

I've tested various "corpse utilizing" skills in a fully "cleaned" map to see whether I can fully get rid of these corpses lying on the ground -

Raise Zombie - zombies raised, leaving bloodstains on the ground. What's more, dead zombies can be left permanently on the ground.
Bone Offering & Flesh Offering - corpses explode, leaving bloodstains on the ground.
Corpse Explosion & Vaal Corpse Explosion - corpses explode, leaving bloodstains on the ground.
Raise Spectre - Neatly cleans an area of corpses without anything left on the ground. Dead spectres vanish without anything left on the ground. Great skill.
Devouring Totem - to be tested since mine is missing...
Minion Instability - to be tested.

p.s. Dead devourers will create a pit on the ground. Nothing can have it repaired till now.

Why I raise this (seems trivial) question? For not these corpses are ugly or disgusting, but for their ability to consume computational resources even when they're dead. This issue exacerbates significantly in several boss fights, the most notorious one is Dominous - if your dps is not good, or dying a lot, or be a zombie summoner, the battlefield can be layered with corpses which will lower your fps to 10 or less.

A lesser(or the user has prepared mentally) issue is from maps with "fracture" mods.

If there is an "environmental cleaning" skill, or lots of them, such performance issues will at least become alleviated -

- make skills with ignite, shock or freeze potentials have chances to burn, vaporize and shatter corpses(the final one has been achieved). Casting them on corpses has the same effect as on living. Some skills(e.g. Flameblast) can be designed to process large quantity of corpses.

- make these aforementioned corpse using skills ultimately "clean", that is, leave no bloodstains.

- make dead zombies corpses again, no dumb objects. Dead zombies cannot be raised into common ones again however.

Whats the point of this though?

He's saying for performance. But I've never had an issue with such... Makes me wonder exactly what hardware he's running on...
