Re: New concept
Your point is well made.
Contributors might however be leery of spending much time on a project that requires copyright assignment to the entity that coordinates the project in future, thus leading to a chilling effect on new projects.
Without copyright assignment, changing the licence like this would require consultations and unanimous agreement I think.
