When I am going to test some mods or other mechanisms or building something in creative superflat mode, the pesky slimes are always disturbing it! Plz remove slimes from superflat creative mode! Plz fix this so that no slimes could be automatically spawned in superflat creative mode. If I want to spawn, I should spawn it with a spawn egg!

I downloaded a mod named "No slimes in superflat mode" , It removed all slimes in that mode. When I was going to spawn with a spawn egg, no slimes spawn! I want to test slimes sometimes but slimes sometimes disturbs me in my other tests.

Plz fix it Mojang!

Thank you!

I have the problem in 1.16.5 and 1.17 both.
