This is cool. I just installed goaccess and was using that to look at the nginx logs but this is also neat. I like post-hoc analysis of these things rather than injecting JS just because it's easier for me to manage for my personal sites. Thank you.
Pick a slight variation on the name, look through the unmerged upstream PRs to find some "obviously good" ones (or to fix other deficiencies you noticed personally), merge them to your fork, and who knows ... your fork might become the next popular home of the project!

JS tracking leaves out most bots as well. They were a nuisance with this method.
