¿Will the resolution of this issue fix the fact that the current glTF export flattens all of Blender's collections into a single level?

For example, this .blend scene graph:

Becomes this single-tiered structure after a round-trip through the glb export/import process:

If this issue fixes that problem, I would like to put a little ETH on it through Gitcoin. The scene graph is so handy for describing nested relationships, and I really wish we could get access to it when rendering glTF files.
