One thing I noticed when looking at the Spiritus, Ignis, Metallum, Terra and Tenebrae is that the pages are filled with every spawn egg added by every single mod. I don't have any mods installed that make them obtainable, so this info is effectively useless. It tried removing them from the thaumicjei_itemstack_aspects.json list but it regenerates every time you start the game, so that doesn't help much.

Perhaps a blacklist feature could be added so that players can blacklist items that contain aspects but should not show up in aspect lists.
Alternatively, items in aspect lists could not show up if the player has them hidden in JEI.
