That is not a counter-argument to something related to this 
library but everything that lies in global namespace.
At its first state both severity levels and the "log" was in 
global namespace. Now only severity levels.

You are also overlooking one crucial fact that this library will 
be part of phobos, standard library. Which requires everyone to 
adopt. When you see codes like this (below), you don't blame 
standard library designers do you?

using namespace std;
int cout;
