If you learn how to handle yourself, there will still be plenty of fun, rad things to do in the backcountry. Every year is a bit different. You do get deeper snow packs there, so once that layer get buried more than four feet deep, it shouldn't be as much of a concern. Of course the other layers could be.
I believe the number that a skier or snowboarder effects the snow pack is roughly three feet deep. I generally dig my snow pits down to around 5 feet deep max. Of course that doesn't negate deep slap instabilities, which are scary, and are a lot harder to figure out. If you hit a deep slab instability, you're messing with a stone cold killer.
