> SAF cannot be used, as it is for sharing/exposing our files to other apps
SAF can be used. There are reasons why this wouldn't be a good fit for NextCloud (you can't share your entire internal storage, your download folder, or the root of an SD card, for instance), but I don't think NextCloud's statement makes sense.
The point of their app is to backup an entire folder. Sharing from one app to Nextcloud doesn't provide ongoing access to backup later versions of the file.
Just to make sure: Google software has the same exact permission structure across the board? e.g. No Google product uses the same permissions NextCloud is seeking, and instead, they are using SAF? Especially for things that do what NextCloud is doing here.
I just want to be sure that Google is playing by the same rules they they put out for NextCloud and other app developers.
Entirely correct, for instance see
