Work with Mixamo to get Quadruped rigging to UE4 standard

I have a request, I would like to see Quadruped and X-ped standard rigging like Epic and Mixamo did with the humanoid characters. If Epic did this, it would set the rigging standard so animations can be added just like the process is done with the hero character. Also it would make creating living environments quicker and prototyping faster. Plus if this happens, then in later versions of the Unreal Engine there is a standard hierarchy of rigged bones.

Well that is my opinion
