Are layers light on resources? If not, would it be better to be more creative about layer usage?

Hello, I wanna switch away from using instance_create_depth and to transition to instance_create_layer, since depth is getting a bit messy for my liking. RN, I have 15+ instance layers, for enemies, interactables, players. and their respective particles. I could cut this amount down by a decent amount, but I would like to have full control over the layers, for example having a dedicated layer for particles that go over the player, and particles that go under the player, and I prefer having a more direct solution.
However, if instance layers are resource intensive, I'll bite the bullet and cut back.

TLDR: I was wondering if instance layers are resource-intensive enough for me to want to optimize the amount of instance layers in a room

go nuts

the biggest drawback to a zillion layers is managing a zillion layers

Late reply but thats great to hear thanks 4 confirming

Slightly unrelated but is depth managing resource intensive? I have heard some saying stuff like that but i have no idea whether thats true
