I agree that we have to be very vigilant against the what ifs, but with the exception of logging, which is the one I most disagree with (unless it is helping you debug a failed test), these all seem like cases where the future thinking thing takes precisely as much time as the ship-it-now thing. The versioning thing could get really out of hand too probably now that I think about it. But timestamps, many vs two, and the "uh this is starting to sound like a database, lets use one" are all effort neutral.
