Do you actually need such a functionality in any applications?

falling back to the last day of the month is a perfect "mathematical"
fallback as well. It's just a matter of documentation.

I understand this if you actually need the functionality you described
in any applications. Otherwise, I'd hate to type
add_month_or_fallback_to_last_day each time I need this simple
