As a matter of fact, a lot of the security credentials (SSH keys, passwords, etc.) are rolled on a regular basis already, as part of institutional security policies.

But I think a point has been missed - the roll of keys on a periodic basis is needed to *exercise the activity* if not achieve a higher level of security.

Presumably there are all sorts of other credentials that control access to the
ZSK (e.g., administrator SSH private keys, root passwords, etc.) Do you also
propose to roll all of these every month? If not, why not?

As with IPv6, the problem with the deployment of frictionless surfaces is
that they're not getting traction.
