This check doesn't appear in the case 2: branch, can it be removed?

I'm guessing this check is to keep handlers like func(event any) {} valid. If that's the case, it's worth adding a comment!

yes.
If the first argument is an interface, the handler may be func(event any) or func(ctx context.Context).
We should accept both.

Wondering if there's a case where this isn't an error. The trival case is (edit) I think of any way that this would be possible with how json.Marshal gets used later, the types it passes in shouldn't have any methods.any/interface{}, where the .NumMethod() == 0 check above makes sense. Wondering if the current version of the code panics if the first argument is error, or some other interface with one or more methods
