I've found to_dict output to be very verbose and in particular filled with empty lists.
Not quite sure if this PR is 100% okay with the author - if it would be better gated behind some argument passed into to_dict then I'm okay to make the necessary changes.
As far as I know, I've never seen a required list field in a protocol buffer, which is why I have proposed the change in its current state
