+Changing the meaning of ``**kwargs`` annotations
+------------------------------------------------
+
+One way to achieve the purpose of this PEP without any grammar
+change would be to change the meaning of ``**kwargs`` annotations,
+so that the annotations would apply to the entire ``**kwargs`` dict,
+not to individual elements. For consistency, we would have to make an
+analogous change to ``*args`` annotations.
+
+This idea was discussed in a meeting of the typing community, and the
+consensus was that the change would not be worth the cost. There is no
+clear migration path, the current meaning of ``*args`` and ``**kwargs``
+annotations is well-established in the ecosystem, and type checkers
+would have to introduce new errors for code that is currently legal.
