I think so. Each time a dependency of acl changes, you get a new acl.
And packages change a lot in nixpkgs-unstable.

I guess so

you can run garbage collection for everything you don't need anymore.
Here are 2 bash functions I use:
function nixos-cleanup-unsafe () {
sudo nix-collect-garbage --delete-older-than "$@"
nixos-cleanup-safe
}
function nixos-cleanup-safe () {
df -h /
nix-collect-garbage
df -h /
sudo nix-store --optimise
df -h /
To remove everything you don't need at all and reclaim hard disk space:
$ nixos-cleanup-safe
To remove everything older than 2 days you don't need anymore (you won't
be able to go back in time):
$ nixos-cleanup-unsafe 2d
