Well, they are only used by integer dates, so why expand their
visibility? The define does make it clear how they are used. I suppose
if someone wanted to use them outside that case, we could open them up.
It is true that with integer dates now the default, we might find that
someone introduces compile problems by using them outside the integer
dates scope.
