This is a rather over-bold claim. What's "more important" depends on
what you're doing at the time. If you just need to bump and rebuild a
bunch of packages on Rawhide for an soname bump (just to give an
*ENTIRELY RANDOM EXAMPLE*, right juhp? :>), then a tool like this is
what you need. Since you won't be scheduling the builds - that's Koji's
job - you don't need a tool that does that.
