How does bumping it before make any sense at all? Maybe it wouldn't
hurt much, but how does it help anyone at all?

i_version must appear to change no sooner than the change it reflects
becomes visible and no later than the request which initiated that
change is acknowledged as complete.

Why would that definition ever not be satisfactory?
