Oh I can assure you they do, but even more they realize the "joy" of your libraries split over two different incompatible versions.  Like I am torn between squeak and pharo for many of the great libraries both packages do have. I can say its "so fun" not be able to use them all at the same time :D not to even start talking about the rest of fragmentation of the smalltalk land between different implementations.

But then I never expected smalltalk to be a smooth ride so its ok.
