Well, you have not said how you think per object settings are supposed 
to work.  In case of a wire grid for example you would have to set 
higher quality settings for both the grid object and the background to 
get it nicely antialiased and if the grid is reflective or if it only 
visible as a reflection in another object it might not work at all 
depending on the implementation.

I understand that per object settings seem like an exciting feature for 
the user because they seem straight away to set up but i have my doubts 
about the usefulness.  Maybe you could post a sample of using this 
feature in C4D.  In case of radiosity per object settings would be 
easier to implement BTW but in most cases it would be more important to 
specify different settings for different parts of the same object.
