The preferred way of adding new features to the Formatter is to subclass it, and modify one or more methods. That's what the existing alternative formatters do.
A user can easily create such a subclass, and use it with their own parser, without having to modify the stock `argparse.py` file.
Given that flexibility, adding new features (as opposed to bug fixes) to the help formatter should have a low priority.
