And that is just the bare statistics. The larger and harder packages (kernel, glibc, ...) are mostly in that 84%.
We seriously need more package reviewers. There have only been a few reviewers and I think some of them (like myself) are already burned out. We also need more collaboration from package owners (famously known as “The Red Hat Engineers”).
(Personally, I guess I will finish some of the reviews that I started and then maybe a few easy ones, but that’s all unless I suddenly find a lot of energy.)
