Is there any reason why meshoptimizer hasn't been implemented in the past ?

Ive been thinking about adding meshoptimizer to raylib. It seems like kind of a no brainer to add, is there any reason why this hasn't been done in the past?

I do not see a recorded repo-side reason that it was rejected.

The current raylib model path loads mesh data and then uploads each mesh with UploadMesh(). The vendored cgltf.h knows how to parse EXT_meshopt_compression / KHR_meshopt_compression metadata, but I do not see raylib-side meshopt_* calls or a meshoptimizer dependency wired into rmodels.c.

It may help to split the proposal into two separate features. One is glTF meshopt-compression decoding for assets that use that extension. The other is runtime/offline mesh optimization of raylib Mesh data after loading or generation. They have different API and dependency implications, so a focused PR for one of those would be easier to evaluate.
