If a package "runlogind" is introduced it would satisfy this
dependency, but...

... pam_runlogind.so would be missing here.  So it looks like arbitrary
providers of logind are not supported, only those listed in the PAM
configuration.

Shouldn't the dependency list `elogind [linux-any]` instead of a virtual
package then?
