Clearly, it *is* palatable, given that a few people have been adding the
systemd mechanism to their programs for several years, now.
Pierre-Yves Ritschard's code and Cameron Norman's code come straight out
of actual service programs.

No, M. Bercot is not. Quite the opposite, in fact. The s6 readiness
mechanism demands *neither* pidfiles *nor* standard output. It's *any*
file descriptor (as defined by the service), and *just a linefeed*
followed by closing the descriptor.
I'm nodding at almost everything M. Bercot is saying here, by the way.
