Do you mean "don't predate the Gregorian calendar"?  I think I might be 
getting my calendars mixed up.  I confess to being confused by the term 
Julian date.

It would be nice to use any date presentation suitable for a selected 
calendar, even outside the normal range for that calendar and to do 
date math on those even when not similar.  Having a default calendar 
would be important.  Getting warning flags for dates outside of normal 
ranges might be nice but may not be practical or meaningful.
