I think this too is slightly beside the point. How I think the quest item inventory works is more like, there is no empty slots to be had, and we actually can have as many key items as we need, at all times. Just since their nature is somewhat limited, their actual amount always stays in check. In that sense, all empty key item slots we have are just graphical. I'd also wager the space needed for saving key items is already much smaller. Unlike the space allocated to inventory item where every item slot potentially have stack size, dye, repair condition, soulbound amount, melds, glamour and inventory position (can't rearrange key items) to be accounted for, key items don't have need for any of those (or maybe for stack size) and naturally the space allocated for them is already smaller for that. Even if we had some amount of space dedicated to them at all times, it might amount to only fraction of inventory slots.
