I feel like you might be miss the point of the parent comment. Synchronizing between databases is a notoriously difficult problem. It's really hard to do while avoiding race conditions. To be fair, I don't understand the "git rebase" technique your project uses, but I'm doubtful it solves these problems.
The underlying issue is that users of SQLsync are going to assume that consistency works, but in suble and unsuspecting ways it won't.
As far as I can tell, the only solutions that handle distributed consistency are those that use CRDTs.
