Fortunately there is no opposition to version control in their group, it's just momentum keeping them from changing.
Their compass to locate "over-engineering" is a bit off track. Engineering starts after you have put your artifacts in git or any other VC :-)
Who in their right mind works without version control? Who would want to? And version control has just gotten better and better over the years. I started with SCCS -> CVS -> SVN -> GIT (with a couple of side treks into Perforce and Clearcase). Currently using Bitbucket/Jira, but have also recently used raw git/gerrit. (The organization makes the choice)
I worked at a large fintech company that had serious problems with this. About the only hope we had for mitigating it was moving all the services to run inside docker containers and of course ban developers from accessing the systems directly.
This made me laugh - not because you aren't right (in theory), but because I just took over a project from a big four consulting company. When I asked about the location of the latest version of the code (after looking in VC and not finding it)...answer: on the production server. "We could have checked it into VC, but didn't want to take the time."
I've seen at least n=6 of these in the past couple of years.
Sometimes the oldies are goodies.
