I don't we will see this happen now even if they were thinking about it..

why you ask.??

well since patch everyone and there pet chocobo has been buying these materials to power level desynth. so if they scaled it back it would make it a lot easier cheaper to get the new demimateria that's required for the now new i90+ gear and weapons in the new recipes.

does this suck.!? yes, because as of patch the cost of so many things have shot up and any new or existing players thinking they can kit themselves out in stuff like vanya, griffen or darksteel have to pay a lot more for it.

so now it is much easier to just run the dungeons and get the free darklight gear and ignore all that stuff altogether. which for most has always been the best choice anyways.
