Dealt with IHIS a few years back. They were implementing a proposed system within healthcare -- basically a specialised database for my team (keeping it vague to not doxx myself) that would be administered by them.

Not liking this but having no choice because I needed the system to scale across multiple users, I asked if we could at least get version control on this little server.

The answer was that they COULD do it but it would be subversion, is that ok.

I quit shortly afterwards. Asked around and know absolutely no one not using git now.
