Seems silly to worry about such tiny little details. We are going to get countless tons of equipment to the moon and you are worried about some debris flying around? How just having a clean landing pad? I was going to say it's not rocket science, but it is. With gravity being significantly lower, landings will be correspondingly lower energy affairs. Also keep in mind that without an atmosphere there will be significantly higher energy micrometeorites with significant velocities. Those are the threats you need to design around, not some shuttle landing in 1/6th gravity.
