Fedora is particularly bad at what you describe. It's basically just impossible for somebody who isn't already in the system (or doesn't know somebody who is already in the system) to get into the system. Between hard to find documentation and requirements like, "just join the mailing list and ask for people to sponsor you" (which nobody wants to do when they don't already know you) you have to really want to do it. I could have easily maintained several packages that I built, but after sinking 4 hours into it (building the packages only took an hour or so), in the end I just threw them on my COPR and called it a day. I'm not going to spin my wheels trying to jump ridiculous non-technical hurdles and try to navigate needlessly opaque processes.
