Change Details

``` It seems brittle to require RPCTypeCheck being called inside the code logic. Without compile-time enforcement this will lead to places where it is forgotten and thus to inconsistencies and bugs. Fix this by removing the calls to RPCTypeCheck and doing the check internally. ``` Backport of core#26039. Depends on D16253.
