Point taken.

However Ben argued, if I interpret him correctly, that services that
on something (a library), should be restarted by default if that
dependency gets
updated and the user should not be required to install an "obscure"
package to
have that sane default behavior.

This implies that an "apt-get install library" needs to trigger that
Which means that apt-get needs to depend on restart-services. So either
restart-services and checkrestart should go into the apt package, or apt
to depend on/recommend debian-goodies, which would currently pull in
perl, curl, dialog and their respective dependencies.

The later may be a technically working solution, but from a conceptual and
KISS point of view doesn't make sense to me.

Is my conclusion correct so far?

So if we want a "clean" solution, then checkrestart/restart-services would
to move into apt and get rid of the non-essential dependencies (get
rewritten in
shell or C).
