What I teach my students (OW to Trimx), is to keep it as streamlined and compact as possible, while maintaining safety and function.
Keeping a console clipped off makes it very difficult to carry stages + o2, and have access to your depth gauge and/or compass. Especially when a dive with a deco obligation comes into play. Hanging on the line in a 2+ knot current with one hand, while fumbling for your depth gauge is needless task loading. Having your depth gauge/computer/compass on your wrists enables you to check vital information (depth, direction ) while maintaining trim. Having your pressure gauge clipped off is rarely a problem, as gas plans and sac rates are discussed / planned for in advance, therefore negating the verification of the SPG every 5 minutes. Not to mention the small size of a 2" SPG which does not get in the way of stages etc...
Although I follow the NTEC / HOG diving equipment configurations, I am not against a diver using other means to rig their equipment, as long as it is safe.
FYI, my open water students start off with a Harness and wing, a bungied alternate reg around their neck, a 40" hose on their primary reg, a 2" spg clipped off to the L waist D-ring, and an ANALOG depth gauge on their wrist. If they buy a computer, it's put into gauge mode until they finish their class. I don't even carry "poodle jacket" BC's in my shop!
