New AzureRM version 4 Provider no subscription IDs for the now required subscription_id

I’ve upgraded to the new 4.0.1 AzureRM Provider. The provider block requires subscription_id to be set, but if I don’t have any subscriptions what would I set a
subscription_id to ?

I totally agree with the subscription_id being required. I almost always set it to be explicit in my code, but now when I’m creating a new subscription it seems to be an issue.
