Requesting the ability to register custom metal seeds in addition to the already existing seeds, moreso in a jaopca fashion rather than a specific mod-compat fashion. i.e. being able to generate a functional metal seed for things like Schrabbidium (HBM), Octine (Betweenlands), or Astral Silver (Metallurgy), with whatever drop I define with support for meta values, such as a jaopca generated byproduct, a Thaumcraft Native Cluster, a Magneticraft Crushed Ore, or a GTCEu Centrifuged Ore. Just as general examples as user-definable entries.
