Question as to project status, maintenance and intended branch

Hey all! I'm considering/trialling using Wikibase in a major capacity for personal usage, and to this purpose, this tool looks like it's currently the most promising for Wikidata/local Wikibase sync. I see there's a master branch that hasn't been updated in a while and that seems to use a CLI as its main interface, and a dev branch that has switched to a Docker-based server model that has been updated semi-recently. Could you shed some more light on where this project is going, and if it's being maintained?

Should I decide that Wikibase the right fit for me and this project ends up being what I settle on for data sync, I'd potentially also be willing to contribute. My python is a bit rusty, but that should be fixable. Of course only if you're looking for contributors or maintainers in the first place.
