Is there something preventing a separate service app that registers itself as an Android sync account from reading\writing to local user-space files, that are placed in a folder Syncthing is syncing, thus automating contacts and calendar sync for android?
I understand the feature was rejected for Syncthing since it’s extra, external dependencies when all Syncthing wants to do is sync files… But is there a technical reason to reject a scheme using a separate optional app?
