Date field should have a start date parameter
When a date field is empty, clicking the calendar button gets you to the current date and you need to navigate through years to get where you want. For birthdate it’s annoying because you need to go back a lot of years.
It would make sense for the DateAttribute to have a start date parameter which is the default date shown in the calendar when editing the field from an empty value. This is not the same thing a default value since the field will stay empty if needed.
