Could someone explain to me why Minions such as Wind-up Dalamud,Model Enterprise, Set of Primogs, etc. Are limited to (First Run Only).?

The physical items are still (for the most part) being sold, and I for one would like to purchase these items. However i'm highly reluctant to do so due to the minions no longer being available.
I fail to see the logic of not having them around anymore on a game that constantly has new players join it.

They even used one of the minions as a boss in LoV.

Can something be done to either.

A. Have the minions added back to Merch.
B. Add them to mogstation
C. Someother means to aquire them
