Thanks for the detailed reply @jjohansen,

Do you think it would be feasible to spawn a pop-up that says something
like "This application uses namespaces which is considered vulnerable to
exploits, are you sure you want to continue?" and ask for the password
to allow the application to run. This would resolve the issue while
still allowing portable applications to run properly. This could be
achieved for example providing a tool to ask apparmor for permissions.
>From my side I can just detect if apparmor is used and ask apparmor to
grant access to namespaces, in term, apparmor would spawn a pop-up for
the user saying that my application is requesting this permission.
