That's a good question. I don't know. If someone else knows the reason I
sure would like to find out.

There are many different reasons to use hooks. If everything that a hook
could potentially need was passed to it as an argument then a lot of
data would often end up unused. Better to supply as little as possible
and only do more work when it's actually needed.

I wouldn't go as deep as the plumbing, I think git status --porcelain
should work just fine, the output is fairly easy to parse.
