When I tested it, nix run only tries to run $out/bin/<package-name> (that's why nix run nixpkgs#neovim doesn't work). So if the symlink is moved to a different location you can't run it automatically anymore.

Right, I forgot about this peculiarity of nix run. It's good to know meta.mainProgram exists now.
I usually always do nix shell nixpkgs#something -c some-program
