Yes.  M-x grep warn_ecpp in gcc/cp/*, then replace:

         warning (0,

with

         warning (OPT_Weffc_12,

and then arrange for an -Weffc_12 flag (or whatever name you like).   
If his new book removes one you don't like, just whack it instead.   
We can default ones that go against sane C++ to off, that way, we can  
restore the utility of the -Weffc++ flag.

No.
