We do not have such a pre-upload hook, but could have one. There's an
old thread from 2011 detailing some potential downsides:

FWIW I think most servers who find themselves needing such a hook use it
to e.g. log how many fetches a given repository might serve, and end up
instead wrapping git commands in some custom shell.

It's also possible to imagine a much deeper integration for such a hook,
e.g. something that would allow you to implement the functionality of
the uploadpack.* variables and more in your own code, but I don't know
if that's the sort of thing you're imagining.
