We also know that the current situation isn’t acceptable to a great proposition of the community, that is why we are still discussing the issue!
A notable example of reversal of an evolution decision is String’s conformance to Collection. Which I think on the 2nd attempt was a much better decision.
For requiring typedefs for associated types, a fix it and error would be quite successful, e.g. Xcode already suggests the typedefs (which I currently accept before letting Xcode insert blanks for the missing methods etc.).
