Unable to invoke a method with `**kwargs` if the receiver doesn't define keyword arguments
This does not:
I may be misunderstanding the idea behind the keyword arguments, but I would expect them to behave similarly to regular arguments when used with splat.

In the current design, keyword arguments are NOT omittable at a callee side.
In other words, you cannot pass keyword arguments to a method that does not support keyword argments.
Other possible behavior is to ignore the passed arguments silently (as you expected), but I'm afraid if it is rather error-prone than useful. It tends to hide bugs.
If you really want to do so, you can use
** parameter explicitly.
** (#7662) is indeed useful in this use case. I'm not so positive to this use case itself, though.
