I used them once upon a time in st-80 ages. Never since.
I would not miss them.
They disappeared quite early from Parplace images (objectworks i think).
Using Smalltalk living organism metaphor, I think they are still here
simply because they are not competing. Thus, they do not enter in the
selection process. Unless we put selective rules on dead code like
you're proposing.
How many % of our DNA is really used? You can answer this question at
the scale of an individual life, or at the scale of hundreds of
generations. Maybe they could make an advantage in a future mutation.
They could as well disappear, or be frozen in a data bank. It's not easy
to play god.
Are Stack and SkipList more used?
Even Bag is rarely used.
LinkedList (Process only).
Heap (WorldState, Zip).
Are there metrics to measure success of a class?
Number of references?
Number of senders of factory messages?
Number of instances in images?
Number of instances garbage collected?
