I really like it too! However I've been using gorilla/mux on prod for a long time now and it's never been an issue, I really appreciate it "battle-hardened" quality and feel.
It's one of the rare libraries I feel fully confident with because it's proved it's with time and time again.
Not saying this isn't true of chi, just that, that wasn't the choice we made for production back then, so I can't compare it at that level yet.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
