I haven't, but it looks like it's a Git repo hosting solution? This issue with using Git with data directly, is you generally loose the per-row/feature change information. With common binary GIS data formats, just putting them into Git looses a lot of the utility and will blow out the size of the repo as you apply changes.

Kart gives you row-level tracking, so you can see who made what change & when, and diffs small and fast to apply.
