If there really is a need for an inventory-less hopper then this is probably the way to do it. Personally I have never had an issue with hopper storage and in fact some builds that rely on it. Since real world industrial hoppers are delivery systems with limited storage I would have hoppers keep this ability, and add a pipe block or something that just moves the item right on through, and otherwise acts the same.
Maybe another solution would be that the items simply bypass the hopper storage if there is any kind of storage like a cart or chest present.
