>Is doing versioning explicitly in a database necessarily more complicated than with git histories?

What "versioning" means depends heavily on the database. "Versioning" for typical relational databases like Postgres does not achieve many of expected git features like branching and ability to materialize data for arbitrary point in time, unless you build something extra on top (or just use db as git storage). There are databases like dolt where "versioning" idea is similar to git.

I always work in controlled environments, so don't care much about tamper-evidence (unless its used for detecting integrity issues perhaps).

I didn't know datomic, that's looks like solution for half of the problem (distribution and history). I may still be missing something more human-focused like git, where you have branches, collaboration and push or pull when needed.

I was just commenting, not disagreeing.
