That's absolutely horrible. Imagine the last two changes were in 2005-01-01
and 2005-06-06. Then if I asked for 2005-05-05 it would give me the 2005-06-06
version, wrong by over a month.

Having a warning just for the exact midway point is equally horrible: the
choice being made does not suddenly become "unsafe" at the exact midpoint, it
smoothly becomes less safe the further you are from either end.
