Now applied, thanks.

I don't know about swaylock, but for CUPS, the change was strictly
required; you can't build the full CUPS without PAM anymore, I think.  I
had tried as a possible solution to the PAM problems.

So the distinction between bound and free-standing in this context is
not very useful (when the changes are forced by upstream rather than
chosen by the contributors).  What would be useful though is increasing
our test coverage to catch these issues.
