I'm being a right dinosaur here actually, and I'm sitting on mainly LTS 4.4
branches or 4.9.

I'm long overdue a major system overhaul, but not sure which way I'll go
yet. I have had some issues with the meltdown/spectre patches on one
system, so I've had to revert. I'm now running the ck patchset, which makes
a noticeable difference in performance/memory usage.
Next step is to change C library over to musl .. but that is a longer-term
plan, depending on when this Big Overhaul takes place ..

That said, I am loosely involved in the Gentoo kernel project, and am
working on the new CI framework for it, so I have access to some clever
people. Alas Greg K-H left Gentoo after the last hiatus (-sigh-) .. so we
can't poke him directly so easily any more.
