The problem with that is, there are now open source game engines coming on the scene that are promising (in the long run, and yes it's a BIG maybe) to upset Unity's stranglehold, that support Python and in the future C# to lure away Unity devs. I'm speaking of Godot. I'm not sure how successful they'll truly be but I, for one, am hoping they bring a solid rivalry.

Python as a scripting language makes sense, in this arena, anyways, as it's the scripting language for Blender. A single scripting language for 3D software and game engine in a game studio just makes sense.
