As per the title, I am requesting that Nether's Delight add its various fruits and vegetables to #createaddition:plant_foods, and its various plant items to #createaddition:plants. This will allow ND items to be used to make C:C&A biomass, without players/modpack devs needing to add all these items to these tags themselves.~
More specifically...

#createaddition:plant_foods should contain
nethersdelight:propelpearl

#createaddition:plants should contain
nethersdelight:crimson_fungus_colony
nethersdelight:warped_fungus_colony
nethersdelight:propelplant_cane
