Then it is a bug, depend means it will be installed, recommend means
what it says, it is recommended to install it, but you do not need to.

Easier way out of this, stop using debian and use Devuan instead.

As I said, apparmor has nothing to do with Samba, the same goes for
selinux and, in my opinion, they should figure out how to work with
Samba, not the other way round. The page on the wiki is supplied as a
service, but Samba has no real way to know if the settings are correct,
it relies on feedback from users.
