Carpets seem to solve the problem as far as the heels not punching holes in the floorboards. The force distribution is probably still way out of line around the heels though as carpets aren't all that stiff, but let's not think (leave alone mention) that!
Definitely a can of worms.
Yeah, explosive decompression is considered these days. For starters, you are not alloved to cover the entire cabin floor with cargo, spreaders or lining. There has to be gaps large enough for the blow-out panels to do their job.
I'll go over to the yaw thread and see what is brewing.
