Looks like a solid basic implementation, along the same lines as Django migrations or Alembic in the Python world. I always find these tools a bit lacking though. Over the long term, things that I find mattering are: - Correctness of changes being made - Support in getting to Zero-downtime migrations - Support in CI around testing against the right schemas - Squashing changes/garbage collecting after a given point - Support for applying the same change to multiple production environments (where you can't rollback one because another failed). These are all hard problems! Some are quite specific to certain kinds of application too. But companies always seem to end up building custom tooling for this sort of stuff. I'm sure there's a place for a tool that gets the right balance between support for these complex use-cases and defining a way of working.
