I just took a look at the RPCS3 PR history, and it doesn't look that bad. (Certainly worse than "no slop", but not what I'd call a flood.)

I went 10 pages back on GitHub, and the overwhelming number of PRs look like good PRs that have been merged. There's really only a single handful of rejected slop-looking PRs. (And another handful from a single user who seemingly didn't know how to use Git/GitHub and was turning local non-compiling commits into PRs somehow.)
