I'm not arguing "merely".  I'm arguing necessary. I'm not arguing 
sufficient.  Arguing "Don't plug the leak in the boat here because there 
is another leak over here as well" is rather weak and seems to be the 
straw man of the Microsoft coprosperity sphere lately. But I'm in favor of 
plugging all of the holes.  Let's have an extended conformance class and 
an unextended conformance class.  Let the market decide which one they 
prefer for any particular use.  Do you have problems with that?
