Isn't it the same with channels though? On my system `/nix/var/nix/profiles/per-user/root/channels/nixos` is a symlink to `/nix/store/[...]-nixos-23.05/nixos`.

Yes, but channels are updated less often and it's very unusual to put an application git repository into one.

You might have two dozen flakes in your system. You'll typically only have a single channel, if you use them.
