This doesn't seem like an accurate description of #762194. #762194 was
not specificlaly a request for the TC to override the maintainers of
"init" to change the alternative order. The TC was more generally
debating whether the switch to systemd as the default included a switch
of existing systems to systemd, and if not, how to only switch for new
systems and not for upgrades (for which the TC solicited proposals).
Changing the init package dependencies (and changing debootstrap, d-i,
etc to install systemd-sysv for new installs) was one possible
implementation of the latter.
Here's an opening paragraph that seems clearer to me about the overall
purpose of the bug report and this statement:
In #762194, the Technical Committee considered whether upgrades of
existing systems should continue to switch to systemd by default, or
retain their init system (with only new installs getting systemd by

For clarity: "to transition upgraded systems to systemd by default, not
just new installs."

I would change this from "non-standard inittab configurations" to "uses
of /etc/inittab". They're not non-standard; it's not incredibly common
to modify inittab to launch services or add consoles, but it's not by
any means non-standard. I don't want to see anyone (such as a sysadmin
of a system with such a configuration) taking this TC statement as a
comment on the appropriateness of such inittab configuration.
Also, you might want to include a link here. The mechanism was being
developed in a thread in #765803, but that's not the subject of that
bug, and that bug doesn't seem like the right place for it. Thus, I've
re-posted the WIP code to a systemd bug, #761063.

Nitpick: "on how to opt to remain with sysvinit on upgrades, or switch
to sysvinit for new installs". (Also, "how to opt to remain with" seems
awkward; perhaps "how to keep using"?)

One potential addition:
5. The CTTE advises (without overriding any Debian contributor,
maintainer, or team) that any such mitigations should be included in
jessie, to ensure a smooth transition for Debian users.
(Since neither (a) nor (b) above has actually made it into jessie, or
unstable for that matter.)
That said, such advice may be unnecessary and superfluous; I'd hope
that's already the plan.

I would suggest inlining this reference in the relevant paragraph, or at
least making it a footnote right after that paragraph, rather than an
