To my understanding, works can be developed and also used privately by the developer in the case where the licensing combinations do not permit copying as coverd by copyright law.
Why do you think that? Can you elaborate?
The GPL license is a conditional permission to do something that would otherwise be forbidden by copyright.
Copyright does not prohibit such development, so no new permission is required.
For the same reason I can buy books and build a castle out of them, or re-order the pages or write my own stories based on them even including large parts of the original book. But I may not distribute these works without permission from the rights holder.
