Not that I know where I come down on this yet, but as far as messing with Nature, that bridge has been crossed, hasn't it? Restricting light for everyone is the idea of combatting the already messed-with genes that make them lay like crazy and contribute to killing them sooner than their forebears.
Just a sort of related side note on this - in reading about heat stress and what can be done for chickens, I read how restricting feed during the day when it is hot is a strategy among others, because it keeps their metabolism lower during the hottest part of the day. Then, to avoid or lessen weight loss, provide feed (this is for an agricultural, mass chicken farm setting it seemed - they wrote something like "lower the feed trays") late in the day BUT also keep the lights on longer, so that they will eat longer, and then metabolize it at night when it is cooler.
