Basically, there's no way to get UUA in the game anymore, so why not bring back the old recipes, for servers to use if they want. Would also allow you to use you old UUM (which if you convert to a new modpack would be UUA now) if you have some left over. Server owners could use UUA as a kind of currency if they so desired, since it can only be spawned in and not created. Long live
