Today I've tried to enable the new Dev Hub for some of our Developers. Dev Hub itself is working only for me as I am using a Salesforce license with the Profile System Administrator. Since the Devs are not involved in selling activities, we use Plattform Licenses (Force.com) for them.
Now the devs should be able to use the Dev Hub.
I was able to create the Permission Set as described here.
But as I'm trying to assign the permissio set, I get only an error complaining about the license type.
Is there any way to allow these licenses to use the dev hub? If not, why such an restriction? It does not make sense to provide them with a Sales Cloud License.
Salesforce plans to bring a new License type for this come Winter 18.
