Exactly. The versioning system is definitely unique and controversial, but I think it fits for a fast moving project like this, so I don't have to really consider versioning which could slow development. When it becomes more stable, I'll likely move to a more traditional semver scheme from 1.0.
There's the commit hash. Basically the "version number" is the commit hash, the human-generated (version) numbers added to it are merely progress indicators, which might be randomly useful. But for a project that has 1 branch, 0 tags and nearly 2000 commits, that's not really important.
yes, the entire exercise isn’t important. It just breaks the monotonicity that version numbers typically have. At that point, just call your version <progress>.sha
