It would be nice and much convenient to verify a patch to build packages on all supported Fedora releases and EPEL 6/7. For example of rpkg, each time when a PR is created, I want to verify that PR by building on f26, f27, 28, rawhide, el6 and epel7, which is what I'm doing by running a script manually by myself now. But, it would save much time for me if simple-koji-ci could do it automatically.
