NTFS technically can store symlinks. Is there a sane tool for creating
them is unclear. Maybe there is a sysinternals one. Cygwin uses a
umsdos-like workaround that works even on FAT.

In all-packages.nix you use real file name only. I suppose that these
symlinks should be there to help find the place you are looking for.
once you decided where your package "physically" goes, you just put it
there and write the path in all-packages.nix.

In my opinion there will not be any redundancy for you if you want to
ignore pkgtags/ directory alongside pkgs. Those who want to use it would
find some - probably redundant - symlinks that will help them to
understand what in nixpkgs structure corresponds to things they expect.
