I just hacked something up these days (not for 3.7.0 though); the change 
would also include a scaling factor for the "specular" value that is 
dependent on the roughness, so that specular and reflection can be 
easily "synchronized" - it seems to me that one doesn't go well without 
the other. I haven't yet tried it on skin though.
