I just begin tests with glFT (v2.0), so I don't know much about it but this work appears a nice solution to export a whole blend file.
As far as I know, and if you only export meshes + images textures, collada works very well, But of course, if you want to export animations/rigging, it could be more complex, maybe due to naming conventions. Let's hope that the Ragdoll system will fix this.
Anyway, for my part, I use Blender for 2 things only: Modeling and texturing. For the other stuff, I think more wise to do all into Godot.
