Just three short things that I think capture the difference between  
your and mine view.

Yes, it will capture changes based on assignment of earlier unassigned  
codepoints as the algorithm is based on an algorithm based on the  
Unicode Properties, and not a table. No, it will not capture later  
additions of unassigned codepoints to the exception table. What is  
needed is "only" that the Unicode versions are updated, and that  
happens when the operating system is updated. Much more likely than  
software / application updated.

My statement on interest from application creators to include filters  
in their applications are coming from, well, application creators.  
They want to do implement these filters.

Last issue, noone want software to "never be updated". But  
applications are much more seldom updated than what anyone wants.
