Okay for the sake of argument let's say that makes sense to me. Should SELinux not somehow communicate this to the user.

First we had the scenario where selinux denies and not logs denials (user space object managers) and now we have the scenario where
selinux allows even if there is no rule to allow it

As a policy writer it gave me confidence to know that "if selinux blocks it logs" and that "selinux denies access by default". Now that those things turn out to not be true. Its a black box. voodoo.
