Horrible idea. You’ll likely end up syncing a mess of unnecessary, incompatible and conflicting binary build files onto different platforms, you’ll end up with internal file conflicts that are impossible to properly resolve and will destroy your repo, especially if you’re still using git on top of it. Don’t do this. Git has its own synchronization mechanisms for a reason, they are extremely mature and specifically designed for maximum efficiency, safety and correctness for the task at hand, which is managing source code. Millions of people use git for source code every day. It is a solved problem.
Syncthing is literally the WRONG tool for this job. It is a great tool for many situations, but you are using it as a hammer when what you need is a saw.
…using this one simple trick!
