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.
