I don't think Guido is *against* future-proof formats per se, he's
against them when they have a cost compared to non future-proof ones.

The proposal I made (a (integral part, float fractional part) tuple)
doesn't have a cost compared to the plain (int seconds, int nanoseconds)
tuple proposal.
(of course, you can also have nanoseconds as a float, but that starts
being weird)
