This will allow us to make changes to `programs.<name>.package`-type of
options found in NixOS, home-manager, etc. but it is expensive at the
cost of a rebuild which depends on the package.
This is to make checking with flakes a bit easier. Though, there are
much better ways to integrate this even with just the nix-command
experimental feature.
Now, there could be multiple wrappers within the configuration but it
should still result with one derivation unlike the original version.
This could be handy for making package overrides with multiple binaries
(for example, 7Z) while making the interface consistent. This turns out
to be way nicer than I thought which is a good thing.
