http://akozumpl.github.io/dnf/user_faq.html#for-my-stable-fedora-release-can-i-install-the-rawhide-packages-for-testing-purposes While sometimes with some packages this works fine, many other times this leads to people who don't understand pulling in large piles of rawhide packages mixed with their stable release and breaking all kinds of things. I don't think you should be advising doing this there, or at the very least you should add a large warning that mixing rawhide and stable releases could break all kinds of things. This is why we split the rawhide repos out... people were installing random stuff from rawhide and breaking their systems and getting upset. ;)
Thanks for the report, we'll take a look.
