It is indeed, but within the context of this overall discussion, note that BeOrg doesn’t support SyncThing.
There isn’t an alternative for that particular user case without dual-syncing with another sync provider. Best I can tell, there are zero iOS apps of any kind with SyncThing support.
You can (and I have) configure SyncThing to track and sync changes within the iCloud app directory corresponding to BeOrg. It definitely feels janky and I worry about file corruption.
