An M1 tank is 'utterly functional', but you wouldn't use it for shopping trips at the weekend.
Does a supposed 'minimalist' BCD require a chest strap? integrated weights? hip padding? shoulder padding?
Those are 'wants', not 'needs'. Minimalist addresses 'needs' (with the modular option for 'wants').
You realize the ZUMA rolls up no bigger than a t shirt? It has very little of anything including a plate. The wing is modular and will come off of the harness and since it is intended for warm water travel, of course it has integration pockets. No warm water diver seeking a super packable, travel BC is then going to want to tote a weight belt that is larger than the BC. I think you guys are confusing a travel BC with a tech BC. The ZUMA is a wing with a harness and two weight integration pockets and nothing much more.
BTW, all of the "travel" soft plates that fit to the mini-wings (18-24 pound) will not support negative steel tanks. They were intended for aluminum 63/80 tanks. Negative steel tanks will tend to roll off the diver and twist the fabric soft plate or the tank will flop side to side. I have the Oxy and the SP, both roll and flop. I love both for their intended purpose which does not include general purpose diving with a 10 pound negative steel.
In terms of minimalism, as a life long practitioner, I am weight belt vs weight integration neutral, I do not see one as more or less than the other. If you are using a BC, a complication to begin with (since we are talking travel BC which by definition were intended for warm water use only), then the addition of a weight belt is more, not less. More to carry, more to pack, more to lose and a lot of little people, do not really have room for a weight belt. That is a thread I have seen before. Even with a small plate, my wife would have little room for a belt. And since she has been a diver, YMCA, 1979, well, weight integration is a good thing for her, no more weight belt struggles or it falling off.
