Hooks are not external because they're not trusted. It essentially
amounts to allowing someone to download an arbitrary script or program
onto your computer which you then execute. It's extremely unsafe, and
is intentionally not possible. To get hooks in your instance, you have
to _manually_ install them. This gives you a chance to _review_ them
before they start executing on your system. Any other approach and the
hooks become an attack vector.
