The thing here is that the 1/4 wave is the minimum that the very
conservative spec is trying to meet.
When people are doing 1/10th wave or better optics with plate glass (not
really annealed at all to any particular spec) and the glass stays that way,
anything reesmbling fine annealing is more than good enough to do whatever
you need to do.
