I've been in the industry for 25 years and have never seen it done that way anywhere. First place I worked used PVCS then migrated to Clear Case. The first free one I used was CVS. I'd say each predecessor had about the same level of penetration, which was 'nearly all'. CVS->SVN-GIT. Git will be replaced. It's ripe for that - its interface is terrible, storage is now cheap, and many companies have no actual need for decentralized version control and the complexity that comes with it. Easiest to use of the bunch is still svn. You can teach a developer everything they need to know in 5 minutes and there's 3-5 commands total you'll need to use ever. I never once saw anyone get into some nightmare state they needed help to dig out of like I've seen routinely with git.
