Hi!
I cant believe i completely forgot to mention this during all the Wormwood talk over the past few weeks. Goes to show how accustomed to it i have become, i forgot it was even a mod!
I can say with 100% certainty i would not have bought The Hollow, The Triumphant and the Roseate if this mod didnt exist, no matter how much i love the models of those skins. They feel incomplete without a matching flower trail. Im pretty sure this mod alone has convinced a lot of people to buy a certain skin.
The base flower trail can work for the Oasisbound and the Pumpkin but it looks super out of place with darker themed skins. Especially now that we can enjoy the pretty Blooming model throughout the year and not just ~3 days in spring.
So yeah! i think a lot of people would appreciate it if this feature was made official, so we dont all have to depend on the charitable work of this modder for future skins. 
ps: for those unaware Wormwood Flowers Extender gives each of the skins a fitting trail of flowers when in bloom.
