More apparmor questions - profiles?

There are a few profiles already set up in apparmor.
However there are a few things missing since Arch has zero premade profiles (not even in the AUR, it seems). So no profiles for cups (which is the big one, security-wise I guess), browsers, transmisson…

Is there any place to find premade profiles? I tried creating my own for Vivaldi but it was just undoable.

you can open ubuntuuuuu in virtualbox and peak at it ?
