And, even if we go an entire "season" without zone changes, leap second
data expires twice-yearly as well whether there's a leap-second or not:

Even if there are no zone changes in the Mar/Apr season, we would still
need a release around May to incorporate the Jan announcement regarding a
possible Jun leap-second.
Even if there are no zone changes in the Sep/Oct season, we would still
need a release around Nov to incorporate the Jul announcement regarding a
possible Dec leap-second.

So the point about avoiding atrophy is well-taken, but I don't foresee us
dipping below a minimum of two releases a year.  And because of the above,
I also don't see the need to impose any further arbitrary schedule on
releases either.

Yup, no avoiding that.
