Depends on if there are any 'gaps' in available flora resources. Are there categories(food, textile, medical, etc) that could be shored up to offer people more flexibility in play styles?
An example would be in the vanilla game, collecting aloe is the only way to make first aid bandages. That then requires trips to desert biomes and with no way regrow this resource(pre-A15), a basic item can becomes something far more difficult then it should be. The creation of something like the plantain or comfrey plant in the vanilla game could fill the same niche as the aloe for non-desert dwellers.
