One crucial difference I was able to spot is that Demikernel seems to have an approach that can work for OSes other than Linux. To wit, examples of the performance of the Demikernel approach are shown on a Windows system running in Azure.

Of the three examples you listed, none of them seem to support their kernel bypass capabilities in anything other than Linux.

Fair enough. My guess is that the commercial solutions are simply going where the money is. If there was a commercially pressing need to port to other systems, I’m sure it can be done.

With that said, it's one thing to have a legitimate reason for preferring an alternative approach. But the paper doesn't even mention these solutions, which means that the authors are either ignorant of what's already been done (bad), or deliberately avoiding comparisons to alternative approaches (worse).

I would put the reviewers on the spot actually, even if the authors weren't aware of such solutions, the reviewers should.

This is the trouble with submitting to OS conferences. Their networking knowledge is typically limited. I’ve seen the same thing happen in the past.
