document ability to disable MACAddressPolicy
While it is currently possible to either not set MACAddressPolicy or set it to a value different from "persistent" or "random", it is not obvious that a user can do so. Add a policy, "none", which simply retains kernel MAC addresses (same as not filling in the policy at all) and document it so that users are aware of this setting.
