What's problematic about it is that it's slightly easier to do the wrong thing. It seems insignificant, but 98% of times you use use, it's going to be wrong. Also, 'use only' means I have to change my calling NS twice in different parts of the emacs buffer any time I change a function name in the called namespace.
