Oh, I missed this one, so you don't care about users? 

Users often pay to distros for support, and distros always turn to vendors
for debug situations, in fact one of the high stakeholders for this is an
enterprise distro..

Also Jason and I are users, and more than 300 engineers at nvidia
and dozens of customers are users, deploying 100s of thousands of ConnectX
chips in their fleets.

if it weren't important for us and our users, I wouldn't even fight this
hard.. but it is important, and very useful, I can't express that hard
enough.

So you don't care ? Then don't ask about who the users are, in the other
email, apparently it's all about your personal opinion and views about
vendors what drives your responses. So it is really hard to debate with
you..
