For me it's not some arbitrary rule, it is about maintaining visibility for other divers. I am lucky enough to own my own boat which may or may not be cheaper than chartering depending on how you look at it but still, when I take a group of people out on a dive its plenty expensive. We also dive mixed gasses that can cost at least $60 to fill a set of doubles. Having spent that money, and taken people on my boat for the pleasure of diving some fantastic Great Lakes wrecks, its discouraging to get down there and find that viz on the wreck has been reduced from 100ft to 10 because someone in a previous team has "kicked the crap out of it." This is especially infuriating if I've trailered the boat a few hundred miles to dive wrecks in another of the lakes.
To me this is not so much a matter of horizontal trim but more of finning technique. I've seen divers maintain a horizontal position but then use a flutter kick that kicks up a dump truck's load of silt. On the other hand I've seen divers use a flutter kick and not disturb the viz at all because their situational awareness is good and they know enough to stay well above or off to the side of the wreck. If you want to see things up close; whether a cave, wreck or even to a lesser extent a reef, learn how to frog kick. After all the reef dwellers would prefer not to be covered with a thin layer of sand and crud too -which certainly gets launched into the water column by poor finning technique. Look backwards now and then while you're diving. Is there a cloud in your wake?
Work on your diving!
It so happens that frog kicking pretty much results in a horizontal orientation in the water. As a rule good finning technique = frog kick, frog kick = horizontal orientation. Ergo; horizontal trim = good diving technique.
