Not sure if this is the right place to put this. I'd like to suggest the addition of a built-in support for obj. models. I'm currently using and writing documentation for morimori's SpecialModelLoader, see here: https://github.com/TeamFelnull/SpecialModelLoader/

Forge includes a loader for the .obj model format: https://docs.minecraftforge.net/en/1.19.x/rendering/modelloaders/

Would love to see something like this built-in to Fabric, thanks!

This is out of scope for fabric, the libraries already handle it nicely.
