I have commented on the bug. TLDR: they have never been formalized as
fdo spec, but they are documented by systemd and are official API of
it. if you want to make them an fdo spec, by all means go ahead, you
have my support, but I am not going to do the work, for me personally
systemd docs are good enough ;-)
