Depending on what you mean by «being a (linux distro) standard», I think
you're misunderstanding what at least I meant, and quite possibly what
Russ Allbery meant too.  (Russ, please correct me if I'm wrong, I don't
want to put words in your mouth.)

This is about how systemd is maintained, not whether it is (or can be) a
standard tool.  systemd is not maintained by a standards committee.
It's not driven by people sitting down, discussing the problem it's
trying to solve, thinking about all the edge cases and then writing a
spec and documentation for what one has thought about.

systemd is not written to be interoperable with other init
implementations or a tool which you can easily switch to and away from
it. (You can do that if you don't use most of systemd's features, but if
you commit to using systemd units, there's no other init system that
currently understands them, for instance.)

This does not mean systemd can't be a standard tool, it just means it's
by itself not a standard in the sense the the FHS, the LSB or the XDG
specs are standards.  From talking with upstream, it's quite obvious
that they want systemd to be the standard init on Linux systems.
