Yeah, but it's not something that should require a manual action --
especially considering that implementing this well is easy.

Right, but with the reversed order. This might be a bit unobvious, but:
• on all systemd installs, the dependency is moot (no matter the order)
• on non-systemd, your ordering would make apt try to switch inits instead
of pulling in anacron
• the only case where non-first dependencies are ignored, B-Deps on official
buildds, doesn't matter for a task package

Which raises a question: why would we want that redundant systemd timer?
The cron job can serve everyone, timer only systemd users. Twice the work,
twice as many configurations to test -- for no gain.
