The thing I liked about thin arrows (other than the conciseness) was the lack of a prototype object, thus automatically throwing on construct and having similar behaviour to native functions. Concise methods and fat arrows already have this behaviour, but if you want to add such a method to an already existing object you have to resort to using Object.assign (or have a function with a prototype that is made to throw on construct).
Of course, if we made .prototype configurable for non-builtins we could always delete to get the same behaviour. Not sure how viable that is, or if it's worth it for such a minor convenience.
