While projected doesn't seem required in my tests with GKE 1.16 it is mentionned as part of the recommended minimum set of allowed volumes for new PSPs in https://kubernetes.io/docs/concepts/policy/pod-security-policy/#volumes-and-file-systems.

Note that we could also add downwardAPI and emptyDir which are also part of the recommendations (same for the other charts)
