I think I can agree with that last part. Mix-ins would accomblish that, maybe 
/they/ are missing in squeak, not MI.

i guess the reason why theyre not present lies in the fact that mix-ins can be 
emulated too easily via doesNotUnderstand:. 
I guess enhancing squeak to support real mix-ins would be a matter of one 
afternoon. I'd rather support that but MI, though I'm not sure if either of 
both is really needed.
