Now that’s a surprise, i will try it out immediately, since what always made me dislike blender a lot was mainly their alien cockpit. 
Just noticed the grid in blender looks exactly like mine, even the division
A main reasons i use a converter between is that it bridges any missing features and project specific features like generating impostors. Also that glTF is a generic and common format, using a custom binary gives me more specific control like for progressive chunks and adds a simple but helping level of protection, since a glTF can be directly opened in DCC tools.
