New experience library is missing managed metadata key filter and include descendants filter

I am implementing for a customer a new O365 environment. In team sites I implemented document libraries with managed metadata columns. I would like to implement these 2 options below which are available in the classic mode, but didnt find them in the new experience document libraries:

1) Key Filter

2) Include descendants filter

Are these 2 options will come back in the new experience? Or are they never come back? 

My customer would like to filter not only on 1 term, but also the child terms.

Souces:
