Yup. See also this recent followup from him: https://github.com/frankmcsherry/blog/blob/master/posts/2017...

Literally the papers are "I built a thing, and it gets faster when you do this thing to it." There's no condition on whether the base case is realistic.

To be clear, I don't think the authors of the papers he's taking down are bad people, or maliciously trying to get publications for uninteresting work, or too stupid to implement things efficiently on a single core, or anything. I think they're genuinely interested in the work they're doing, but responding to the pressures of the environment that allows them to keep doing that work.
