I think that would be better.
It makes me think, though, that we don't really have a place to centrally
document what interfaces we consider essential and what ones we don't.
Effectively, anything provided by a package that's a pre-dependency of an
essential package can be treated as essential by this same logic, with
sometimes unintended consequences if a maintainer later wants to drop an
interface. So perhaps we should be explicitly blessing invoke-rc.d as
virtually-essential, with the consent of the sysvinit maintainers, before
changing the example?
(For that matter, /usr/bin/awk is another "virtually-essential" interface in
this category, and we've held forever that you don't have to depend on awk
because base-files does this for us; but that's also not documented in
policy, that I can see.)
