That is an interesting question. Current patchew tester setup never updates the docker image which means fedora:latest or fedora:rawhide won't get "refreshed" at each test run, over time they get out-of-date. We should have a way to periodically update it.. I can also work on a patch to add fedora:rawhide to tests/docker, but I'm not 100% sure that we want to add it to the first class test combinations - there could be noise if something regresses in rawhide. Still, we can make one move a time.
