Oh, i mean you can still have WITH_PM_UTILS conditional in the RPM spec / configure check. Downstream user can thus have the option to have both enabled at build time, or to disable pm-utils and only rely on systemd. ie we'd default to everything enabled and fully dynamic at runtime, but we'd set the RPM builds to disable pm-utils on Fedora >= 20
