What in incredibly weak argument. I think I'll just let it stand here,  
it's actually too weak to discuss seriously.

Ok. Here goes: you are saying "don't touch anything because it's there".  
Whether it stinks or not. I think that's being absurdly conservative. You  
have a pile of dirt on your doorstep and you let it smell because it's  
already there?

Personally, I'm of the opposite persuasion - code smells and bit rot have  
to be battled with any available means. If the available means don't  
suffice, make new means. The refactoring of the Collection (and most  
likely Morphic) hierarchies in itself are for me reason enough to vote for  
its inclusion into base Squeak (given due process, etcetera), because  
frankly I don't know of any alternative solution that comes even close if  
it's about cleaning up these old sores.

Furthermore, by loose induction, I would say that if Traits is able to  
elegantly deal with these two warts, I think it will prove to be a very  
productive tool in the average developer's toolchest.
