And ADB will obey that and won't pull lany backups for those apps.

   Thanks for your information. It might come in handy if I ever
encounter any such apps.
   FWIW, I'm not worried about my banking apps not being allowed/able to
backup their data, because any relevant data can most likely be
recovered from my accounts on the banks servers. I.e. if lost, the
on-device data is recoverable.
   N.B. It would be interesting to know if other computer programs - such
as Samsung's 'Smart Switch' - also honor the manifest settings, but
given my above mentioned low interest, I don't think I will try.

I also very much echo Frank's sentiment to Arno thanking him for edifying us as to why some apps can be backed up and others can't (unrooted).
I, like Frank, am not all that interested in the gory details; but it has always confused me why some apps and file managers can see the system directories on Android while other apps and file managers can't see them.
Specifically I've wondered why I can see a lot of the root system folders when I use adb and webdav servers with Windows File Explorer over USB.
If anyone cares, one file manager which *does* seem to see (read only) system folders on Android appears to be ZArchiver archival program.

It's not supposed to be only a file manager - but it shows the root partition. Maybe Arno can explain why that one archiver shows the file system so well?
Muntashirakon App Manager shows me it has some of the following permissions
android.permission.REQUEST_INSTALL_PACKAGES
android.permission.MANAGE_EXTERNAL_STORAGE
android.permission.ACCESS_SUPERUSER
etc.
