class derived : public abc

abc * ptr = new derived;
delete ptr;
This delete expression won't compile because abc's destructor is protected.
So it doesn't really matter whether it's virtual. For what it's worth I
don't think classes like this have enough pros to outweight their cons.
I've messed about with stuff like...
class wibble : public interface<wibble> ...
class fubar : public abstract<fubar>...
class snafu : public concrete<snafu>...
These are similar, quite nice, but I still don't feel their pros outweight
their cons.
