Remember that if we remove historical transitions that are problematic, 
what we are actually doing is replacing them with a lack of transition. 
The database will still give an answer for these historical 
date/timezone combination. It may well give an answer that is wrong more 
often than it does now.  Before it might have had a transition date that 
is wrong, now it will not have any transitions at all. In the absolute, 
wouldn't that make more timezone with more dates that are wrong than is 
currently the case? If that's so, then isn't this a step backwards?
