I can't disagree with anything said here. I guess it depends on the blade in question. I can't imagine that big Sher Movie Model with a thick flat spined blade with anything but the thick habaki bolster that it has. But my salyan is like Berk's, and is perfect in all respects, and it would look much worse with such a bolster.
As Munk said, I am happy to see it in new models and old versions coming out, especially in models such as the Seax which on my two copies has huge habaki bolsters present, even though it is meant to fit in a sheath, and they look ungainly on that style knife. (I guess to be critical of my previous writing, that model alone would contra-indicate my previous point that it was meant for only scabbard fit, but I think that has been a consideration in the past.) The new Kumar Seax models look much nicer IMO with a standard bolster, as do knives such as the kerambit which have always had it.
However, to follow up on Munk's point, I have no burning desire to unload all my perfectly good habaki bolster knives and replace them with standard bolster models. About the only thing I cringe seeing anymore is cho creep, and then it has to be pretty bad. I have a wonderful 18" villager AK with well done habaki bolster, a razor sharp pointy edge, great unfinished horn handle, all in all a real workhorse, and the cho is at least 2.5" from the start of the bolster! That is just a waste of good blade, and makes the knife look very odd indeed, but that is an extreme example, and I have never seen another that far out. (I am tempted to scribe the underside of it with lines a 16th of an inch apart and just use it as a short ruler! At least I would get some use out of that space!
Bottom line, no matter what they come up with in the future, I'm convinced the overall effort will always be one that drives improved quality and choice for us.
