Indeed. To clarify, because I think there is still some ongoing
confusion regarding binary files and binary packages, here a table:

Debian package name  | (primary) file(s)
--------------------------------------------------------------------
liblastlog2-0        | /usr/lib/.../liblastlog2.so.*
libpam-lastlog2      | /usr/lib/.../pam_lastlog2.so
lastlog2             | /usr/bin/lastlog2 (probably + symlink "last")

I think my biggest open questions for the packaging itself are:

* Which package will pull in lastlog2 and libpam-lastlog2, for
  for upgrades from bookworm?

* Should /usr/bin/lastlog2 be in a separate lastlog2 package or not?

* Should lastlog2 Depend: libpam-lastlog2? Vice versa? Only
  Recommends?
