Except a club can apply for an extension, or even to temporarily bring in the local rule when course conditions warrant.To that end, it would make more sense for preferred lies to be an optional local rule that the club chooses to put in place if conditions allow it. Rather than just a blanket rule from October to April whether you need it or not - and if conditions are terrible on May 1st, tough luck.
I can barely remember thinking "I wish there was preferred lies in place so I could clean my ball" during this summer, but I bet during the winter months every round will have a few instances where the ball has a huge glob of mud stuck to it.
