Hello!
It's not planned at the moment because it's more comfortable for us the current single tls-crypt key. tls-crypt 2 doesn't change anything for the client, while on the server side, in our specific case, it would be useless because we maintain tls-auth for backward compatibility,. Any denial attempt would remain potentially possible via tls-auth, hence we would have a complication for nothing. However when we drop tls-auth (we're afraid not in the near future because of the amount of old OpenVPN versions connecting to our service) then tls-crypt-2 will become attractive indeed..
Kind regards
