You are referring to [1], is that correct?

Is this because it was lack of review or are there any technical 
difficulties/disagreements?
If the former, this is not unsolvable. Depending on which approach we 
go, one of you could review the series of the other.
With my AWS hat on, I would also be interested with the optimization in 
the LM code. So I would be willing to help reviewing it. That said, I 
can't promise any in-depth review before 4.17 is out.
Cheers,
