I think the problem is that the 2.0 crafting material mentality was to have 9 relatively cheap tomestone materials for a single endgame crafting attempt. This was a bad idea because: #1 it created storage clutter, #2 it made crafting rewards in dungeons kind of pointless, who wants only one coke? SE recognized this as a mistake, because from 2.2 onward, endgame crafts only required one of each tomestone currency item (each roughly 9 times the price of what the 2.0 mats had been).
So the OP is asking if those original 2.0 crafting reagents (coke, potash, animal fat, etc) will ever be cut down to needing only one per crafted item to match the later trend. This was definitely something I was hoping for back when I was building my original airships. They could raise the price of coke from GC vendors, while changing recipes to require a single coke rather than 9. Crafting stacks would become smaller, and you wouldn't have to purchase as many items to make the same thing for the same cost.
Then SE finally added a selectable quantity tab to the GC vendors, so that you can simply buy 99 coke all at once to make 11 darksteel ingots. Gone are the days of clicking your mouse 99 times individually. So no... other than stack sizes and making rewards from brayflox HM more sensible, there really is no more reason to reduce the number of 2.0 mats needed for crafting 2.0 items. It's become a minor annoyance only, even for hardcore airship crafters.
