My wife and I both have excellent bouyancy skills and never touch the reef. Really. Frankly, neither of us have any intention of touching anything underwater besides a decent/ascent line. Now, with that said, we have both at some time or another been stung by marine invertibrates in the water column. I was stung by a sea wasp on the back of my leg in Aruba while snorkling while my wife got some sea lice (baby jellyfish) while swimming in the BVIs. Consequently we take the term "exposure suit" quite seriously and never dive without a full wetsuit, booties and, yes, gloves. The gloves makes sense to me for another reason as one is often called upon to decend or ascend on a mooring line, invariable encrusted with some quantity of fire coral. We are going to GC for a vacation soon and, while I know that gloves are "not permitted," I am wondering just how strictly the dive ops there enforce this? Happy Diving!
