He quite reasonably chose compatibility with the existing ecosystem over
dependency on a massive restructuring.  Not that that restructuring is a bad
idea, but without better language support it's simply not worth the effort.

Speaking of which, has anyone formally proposed the class/instance alias
stuff for GHC?  If so, has anyone stepped in to implement it?  Having the
tools to actually make this kind of change would be helpful.
