Thank you for pointing out this work, very interesting!

At the CCWG session at IETF 119, we have had a great discussion on 
potential future work items, with lots of interest in working on 
solutions, especially congestion control algorithms. In addition, at the 
same session we've had quite a bit of discussion about data center 
congestion control and what considerations may go into standardizing 
algorithms here.

If you haven't already, I invite you to read the most recent Editor's 
Copy of 5033bis, which lists a number of considerations that may go into 
CCWG's decision of whether to adopt a proposal in this space, should the 
authors decide to bring the work to CCWG:

I hope this helps.

Best,
Reese
