I suspect some properly weighted divers dive with more weight than they admit to. Having little or no weight is currently considered cool in tech circles. Similarly diving with a near squeeze in the dry suit is also considered cool by some for reasons that totally escape me given my cold water history.
Moving to the mid atlantic coast from serious cold water (35-39 degree bottom temps being pretty common) I was surprised to see how many dry suit divers in this region still complain of being cold in water where I found a 3mm wetsuit and a 5mm hooded vest to be adequate. Part of the issue is the erroneous belief that any more air in the suit than you need to be snuggly squeezed in a dry suit is inviting bouyancy and control problems and the other part of the issue is the drive to avoid being over weighted.
I agree being over weighted is bad, and potentially very bad when you add heavy steel tanks, stage bottles deco bottles, a light cannister and various reels, and then decide to have a wing failure. I also agree you need to use the BC for primary bouyancy control, not the suit.
But reducing the gas in your suit below the level needed for optimum insulation just to reduce the weight you require does not make much sense. So feel free to inflate the suit (just) enough to loft the insulation and don't worry about not being able to control the resulting volume as it will not be a problem in a properly fitting dry suit.
