Think about it though - have you ever heard of a bottle fed baby being fed every hour? Other than Gavin of course. If the bottles didn't continue to allow flow without active sucking, you couldn't over feed. We've been there, in the middle of the night and we think the baby should nurse more. We tickle their feet, we unwrap them from the blankets, but if they're done, they're done. We can't make them actively nurse. With a bottle you can, because there's still milk going in, they have no choice but to swallow.
Instituting a "BF approach" on a FF Mom and baby (and caregivers) would be wonderful - but wow, what another uphill battle.
