Profiles are a convenience implemented with nix. So in the most general
sense, it's not only nixos. With nix-env in fact you have profiles.

It's either a system configuration, or user configuration :)

The start of X is done at system level. If you want not to use X, switch
tty.

Not much nixos specific, it's doable also with other distros. If you
install multiple window managers, your display manager will ask you
which one to use.
