I am sort of agree. In practice however I use comfortable subset of it and then it is simple. This is my (b). I know that everyone has their own idea about what said subset should be but I do not participate in large C++ teams and hence it is not a real problem for me. So yes in general you're right, in practice some people are ok. What's the real percentage of those I have no idea.
