Hi Martijn,

Looking at the purpose of the ballot, the goal is to require *newly issued* [..] *Private Keys *to be stored in offline HSMs*.*

**

The proposed change scopes this change to [keys related to] Root CA certificates and *new Subordinate CA certificates*

I would recommend to scope this change to Private Keys generated after the effective date, instead of linking it to the issuing date of the Subordinate CA Certificate for those keys.

For example if a CA issues a new Subordinate CA Certificate after this date, with an existing Private Key, then the related Private Key would need to be moved to an offline state. I think the intention is only for new keys to follow this requirement.
