Presumably you mean something like using dpkg/apt for a Debian-style system?

I think that only works if a file is actually installed from within the framework. As soon as you've installed a file via npm, flatpak, pip, snap, specialist plug-in, standalone binary, that ancient program you had to install by hand, or one of the other squillions of ways of getting an executable program, you're out of luck and have to figure it out manually.
