We could restrict the table to changing only with versions of Unicode that
add characters. Those periods would vary from about one to two years. For
some recent history, that would have been:
Unicode 3.2: March, 2002
Unicode 4.0: April, 2003
Unicode 4.1: March, 2005
Unicode 5.0: July, 2006
Unicode 5.1: ~Q1, 2008
And the property would only add characters, never remove them.
