How do proleptic Gregorian dates before the Common Era fit into any of  
the use cases that states are used for in HTML?

Insertion and deletion dates are contemporary. Date form widgets are  
meant for airline and hotel reservations and, hence, need to pick  
dates from the near future. The time element is meant for  
microformats, which means that it will be used for encoding current or  
near-future events dates.
