IQM model format in addition to FBX ?

I see how there is much struggle with Blender and FBX to get animated models into UE4 and I am wondering wouldn’t it be a good idea to implement IQM model/anim format into UE4 so that Blender users would not have to struggle?

Here is the format’s description/specs:

Is it not possible or devs just not interested ?
