The window could be shifted just about anywhere, but it would
still be non-Apple-standard, with the consequent cross-platform
problems.

If you use birthdates in a spreadsheet, you may find even 1940
to be somewhat confining.  (The solution, typically, is to abandon
"date" types, and use separate year fields, at some cost in sheet
redesign.)

Having a representation that works for another forty or so years
seems quite appropriate.  By 2029, assuming anyone still cares,
we can reassess the situation and possibly move the window,
since the relevance of 1940-ish dates will have decreased by
then.  ;-(
