I think you have it backwards. IIUC the reason why every Emacs dynamic module 
declares “plugin_is_GPL_compatible” is that every shared library that links 
with Emacs must be GPL compatible, and an Emacs dynamic module is a shared 
library. But that’s just my understanding, of course. I’m happy to be corrected.
