It looks to me less like rediscovering orchards, and more mixing them in with livestock/other crops in a beneficial manner.
I guess if we get into something more mixed then that they haven't really rediscovered orchards, they've rediscovered permaculture!
I've mowed, raked, and baled a fair amount of hay over the years. This involves driving tractors and trucks around in fields pulling easily damaged implements in precise circles. Doing so in the presence of lots of mature trees seems a daunting task...
