Are, or when, will Beginner and Journeymen Imperial Resource Parcels be put back in? Does the Miner trainer have them?

I ask because I understood that they help Miners learn. More importantly, dragon wise, they are good craft XP and hoard value (10 hv per 2 iron bars or 2 slate bricks). Of course, would be nice for dragons to have dragon developed formulas for hoarding (gem based?) vs. biped parcels, but oh well.

Now, the other issue I have is hoard value of Journeymen Imperial Parcels. Steel/Granite are currently set at 10 hoard per 3 bars/bricks. The same as tier II. It should be increased. If granite is worth 12 hoard/brick and steel is 18 hoard/bar . . . then each Steel/granite Imperial Parcel should be worth about 33 hoard (3*11, as tier II is 2*5 for the 6 hoard/brick and 9 hoard/bar).
