You can write your plugin no matter what, because the GPL is about 
distributing, if you distribute your derived work, you must do so under the 
conditions of the original work, and those conditions say that you may not 
impose additional restrictions, taking away the receivers right to distribute 
the received derived work under a later version of the GPL is a further 
restriction.
