Problem is that it is not just that your code that will be broken but
that virtually every .do and .ado file ever written will need to be
checked. This leads to two considerations: 
1) Such a change would be a huge investment by StataCorp, which I think
is much better spent in other areas. 
2) For a very long time the "risk of bad analysis" will actually
greatly increase due to the huge amount of user writen .ado, .do files
and old habits that have not been adapted to the new convention of
dealing with missing values.
