I’m not sure if a new hauler is the answer to the problem, but I do think the request stems from an actual problem.
Bear in mind that the OP is suggesting a mineral hauler, not another ore hauler. Hauling ore is much easier than hauling refined minerals because of the afore mentioned ships with ore specialized cargo bays. Since the release of the Upwell line and the mandatory availability of free compression being extended to every capsuleer with access to a refinery the usefulness of the specialized mineral hauler has been very significantly reduced.
I feel like this brings us uncomfortably close to a unified New Eden where resources are transferred away from the local economies without making a significant contribution to those economies. I think it goes beyond the obsolescence of a ship type and into the realm of draining away local vibrance and overall variety in the eve universe.
I would not deny that compression is convenient. I would say that the convenience, especially when one neither needs to do or invest anything to earn it, leads to a feeling of detachment that lessens our appreciation of the space we inhabit or from which we gather our resources for our other endeavors.
