The development world is much different and entrenched than it was when the move from svn -> git happened. Think of all the tooling, integrations, and automation we use these days. That was not happening 15+ years ago. I don't think svn as an analogy holds much water, tbh

Tooling, integrations, and automation (Including CI) were all things we used at my work when we switched from CVS to SVN almost 20 years ago.

Some people were, yes, but the scale of this has changed in those 20 years as well
