Yes, my intended meaning was that if you're doing that or something similar then I totally get having lots of layers because it's useful. Mostly I've only seen it come up with nix, but I can see how bootc would have a similar deal. That said, most container images I've ever seen aren't doing anything that clever and probably should be like... 2-3 layers? (One base layer, one with all your dependencies shoved in, and maybe one on top for the actual application.)
