Gltf-blender-io: Any chance this will be backported to blender 2.79?

Here's the error I get on a simple cube with a principled BSDF shader and tried to export from blender 2.79:

This script was written Blender version 2.80.0 and might not function (correctly), though it is enabled

The glTF Blender I/O works at the moment for both 2.79 and 2.8. As this version is not final, maybe some issues do exist, but basically it should work in both versions.
As soon as Blender 2.8 is stable plus the major Blender community is using this latest version, probably 2.79 support will be dropped in the future.

makes sense. Thanks. I wonder why it errors exporting a cube. I’ll investigate.
