As per the title, I am requesting that Cultural Delights add its various fruits and vegetables to #createaddition:plant_foods, and its various plant items to #createaddition:plants. This will allow CD 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
culturaldelights:avocado
culturaldelights:cucumber
culturaldelights:eggplant
culturaldelights:white_eggplant
culturaldelights:corn_cob

#createaddition:plants should contain
culturaldelights:wild_cucumbers
culturaldelights:wild_corn
culturaldelights:wild_eggplants
