I have used savevers.vim for many years as a way to recover old versions of files.

It is comparatively unsophisticated, but I need it so infrequently that it has been good enough.

I do like the idea of maintaining a complete snapshot of all history.

This is a good application for virtual filesystems. The virtual fs would capture every write in order to maintain a complete edit history. As I understand it, Google's CitC system and Meta's EdenFS work this way.
