Yes, there was a strong consensus (unanimous I believe) at the security
summit on incorporating the Yama LSM as a container for generally useful
miscellaneous security hardening features that don't belong elsewhere.

This means that LSM is no longer 'officially' only for access control
mechanisms.

We probably need to flesh out criteria for inclusion in Yama and document
