Yes, I agree. I think that would be an additional improvement to gimp's  
jpeg quality. It may be somewhat more work that just deciding what  
jpeg_quality we should be using. Although futher improvement of the way  
gimp handles jpeg may calm some of the "let's stop the user working with  
jpeg" crowd.

Certainly it would be prefeable to improve the jpeg quality rather than  
crippling gimp and restricting the user.
(no pun intended)
