yes, but this approach is realistic - if You zoom in real chrome object You 
will see that in fact it is quite sharp (as in zoom in on www).
And my normal works exacly that way.
I alsow foght about strong AA needed, and imho best solution is to use 
quality optin like

#declare QQ_DetailedNormal = 1;

and when option is "0" - use some i.e. bozo and ignore normals smalle rthen 
i.e. 0.1 (on 50.0 radius sphere)
