I can see the use cases for desktop, but this is the restriction of
Flatpak for shared HPC servers: not all administrators are willing to
grant the users the seccomp and permission for creating new namespaces,
and not all administrators will upgrade or recompile kernels to support
namespaces.  If /app is not available, it is difficult for a user to
override the hardcoded /app of Flatpak into /home/user/app.

In principle, we can create an _appdebian_ by hardcoding /app to every
debian package, not unlike hardcoded /system in Android systems.

Cheers,
Benda
