FWIW I've been assuming that this is wanted for BigCorp people who have devs using vanilla OS's / XCode etc. Having managed laptops with a managed /etc/gitconfig certainly makes some things easier...

Whether you're at BigCorp or not you've got the problem with such a /etc/gitconfig that it applies to all repos, but someone at BigCorp might clone both a BigCorp repo (wants custom config, hooks etc.), and also some random node.js github.com project (should have no such custom config).

Having a .gitconfig or otherwise making the repo suggest/control the config/hooks is an elegant way around that issue.

You otherwise need to do something like have config includes apply a rule to ~/work/, and then hope your users follow your suggestion to clone repos in the ~/work/ folder.

I think extending config includes to e.g. operate on a glob of the remote URI was suggested at some point, which would make use-cases like that easier than they are now, and would be a less invasive change than what's being discussed here.

But right now we don't have that, so we have a gap there...
