Well Yama which has now been special cased, and in the past there has been
discussion about other special case LSMs like case is proposing for module
loading. There has been interest around both selinux + apparmor and
smack + apparmor. I am not sure of all of the use cases that have lead to
such question but some of them have been around containers, with say
selinux on the host and apparmor in the container, or visa versa.
