don't think you'd need more textures for the variations. could be made modular kinda, i guess. i mean you have one leaf and one trunk texture so far. why change that

the way i understood Draco was that you could make more model variations. like not 1 big and small, but 2-3 big and small versions, so people can spread them wisely around. that wouldn't really make the filesize any bigger.
but it's just an option. i totally understand that once you're finished with a model you don't wanna take that step back only for one person

it's not meant to be harsh, but we just have to look on the downloads section.
is it worth to spend another hours long session just to get 3 more downloads.... ?
i think if someone would really ask for more variations especially for his map you could jump on the wagon.
i always get this feeling. people always ask for more textures model variations but in the end they don't even download (let alone use it in their maps). so i'd leave the cool stuff as it is and let people come towards you if they should ask for more
i can only say it again, i think it's some nice work that if lit and placed correctly can really make the map shine !
