Could you explain why we want ArgsToParamsOpt to be default in order to enter this path?

If it's not default it means we know the args-to-params mapping so we can continue. The problem is only in error scenarios where the bad BoundCall does not contain the mapping even though there are named arguments in the call. That's when we want to enter this path to skip further processing.

I'm going to merge before the snap. Will follow up if you have more comments. Thanks.
