Surely it's desirable under all circumstances that

len(u) == sum(1 for c in u) and that [c for c in u] == [c[i] for i in range(*len(u))] How would that play under Jeroen's proposed change?

Yes, but I think the argument is about what "c" is -- a character or a codepoint. Your point about efficiency is well-taken; I doubt that random access to a particular character in a string has to be efficient -- kind of a dying technique these days -- but slices and regexp performance need efficiency guarantees.
