That'll be linux-sysctl-defaults (Priority: important, with a
Recommends from systemd).

That is, we could advise users to run

 apt list \!~i~important
 apt list \!~i~pstandard

or indeed

 apt list '!~i?or(~pstandard,~pimportant)'

and ask themselves what their reasoning is for not having them.  If
only they'd finish deprecating "Priority: extra" it'd be just 

 apt list '!~i!~poptional'

As an aptitude user I've also been in the habit of looking at the
"Audit Recommends" viewer after a dist-upgrade, but I don't know of
any way of getting that out of apt.
