Yes indeed. The trouble is that Sutter writes on this so compellingly, that it feels almost churlish to argue against it. It actually convinced me for several hours when I first read this, but as Kevlin has already said, it's the Template Method aspect that rings the bell.
I wouldn't go so far as to say that NVI is never the right thing. There are some scenarios in languages other than C++ where NVI is a recognisable idiom.

I really do feel that the case is too weak for this to be a guideline, either here or in other recent and influential style guides.

Regards,

Adrian
