Thank you for the clarification. Because you said “it took a small team … and then I resigned”, it was unclear that you were part of that small team and instead made it sound like you left because the problem was fixed.
I worked at a company recently where I couldn't get a team to do the fairly simple task of cleaning up our git ignore (so we wouldn't have to painstakingly add certain files to the index every time we changed something) so I take it as a massive accomplishment moving to git within two years.
If I know anything about work, I doubt this is all they did for two years. Business doesn't care you have an important project. They will bug you to do other things.
