He mentioned this in a conversation, but I don't believe it. AFAICT, 
he's drawing the conclusion from the fact that these cores call some 
functions (or a function) in src/pic.c. But, the functions I've examined 
had a small nugget of code that could be moved out of PIC, so the rest 
of the PIC function could be safely deleted.

CGP is too important to be deprecated over something as small as this.
