It's the opposite, as Manolo explained in his post. The existing
version is
void method ( args ) = 0;
which means there is no default method, you must define one in your
derived class.
The proposed change would add an empty (inlined) default method:
void method ( args ) {}
No need to define one's own method. This may be sensible, if documented
correctly, to reduce work for unneeded methods in derived classes - if
they are really not needed...
