I can see where you're coming from, but just wanted to add a counterpoint.
I recently removed jQuery from a website, and the YMNNJQ website was one of the bits of info that gave me the nudge to do that. The website in question only used jQuery in a handful of places, it was one of the few third party libraries being used (so the % size savings was significant), and I'm fairly fluent with JS... The website simply hadn't gone through a major update in the past 5 or 6 years, and the browser landscape has shifted enough in that time that the pros/cons weigh differently now.
So I think there are scenarios where this info is sometimes useful in the "I might remove jQuery" sense, and not in the "wow, I'm definitely keeping jQuery!" sense.
