On Japsand, which Jenkins builds on, I updated the mock files (/etc/mock/*.cfg) for Fedora Rawhide to their mock 1.2.7-1 versions: https://apps.fedoraproject.org/packages/mock/changelog/
One of the differences is that the rawhide RPMs now have "fc23" instead of "fc22" in their names.
I started rebuilding the Rawhide packages through the Jenkins WebGUI. I intend to finish doing so tonight.
