"systemd compatibility" makes no sense here. We are talking about
runit or s6 as an init system: by definition, in that context, there
is no systemd, no interaction with systemd, nothing that requires
compatibility with systemd.

If by "compatibility" you mean: doing the same things that systemd
does, following the same API, aligning on its choices, then I have
a question for you: are you also in systemd discussion spaces and
asking them to align on the design choices made by s6? Why not?

systemd uses a mechanism that it chose, and that works.
sysvinit uses another mechanism, and that works.
busybox init uses another mechanism, and that works.
runit uses another mechanism, and that works.
s6 uses another mechanism, and that works.
What do you have trouble understanding?

  Ah yes, very accurate heuristics, absolutely up to par with my code
quality standards. 10/10, would throw into the garbage bin again.
