I don’t have a direct commit contribution, but word-of-mouthed using Fedora since 2016 
I made some Coprs for Wine with certain patches: Making sure you're not a bot!
Not sure if there was a better way to go about managing the Copr, but I winged-it; for wine-patches Copr I have notes on how I uploaded packages to it, and after figuring that out I did it for the other repos.
