> Contextful.Fn allows subclasses to declare checked exceptions, but neither SerializableFunction nor SimpleFunction do. We want to add a new entry in each of those hierarchies where checked exceptions are allowed. We can then change existing method signatures to accept the new superinterfaces in contexts where allowing user code to throw checked exceptions is acceptable, such as in ProcessElement methods.
