Programming

The big difference there seems to be cloud, ie someone else's computer, and company internal network. That is a big and fundamental choice: Will you allow (leak) your data outside of your control.

Doing anything with Windows shares is a bad idea technically, of course. But with git, every workspace is generally a full copy of the repository. All you need a shared one for is syncing work. And backups are always a sensible thing to have no matter how you arrange files. With that, it seems to be a low risk thing to me.

A bundle might or might not be safer than a repo, but either will probably work.

Reading some of the comment responses, it does sound like there's an air of ineptitude or a long history of systems not working and devs not allowed to make them work, so they just try workarounds for everything.
