Thank you for reply. I got here when I was evaluating if syncthing is useful for me or not. I was looking for stability, errors etc. before testing it.
The only reason I asked was that this sentence: “Syncing git repos is a terrible idea” is to general and I feared there is some issue. It should have been written in this way: “Syncing git repos is a terrible idea if you have concurrent changes”
World is complicated, there are other applications that have complicated file/directory structures, not only git. And there are documents suitable for versioning, but pushing them somewhere is not needed etc. It would be too complicated to separate directories according if it is or is not git repository.
