Why didn't Koa JS ever get as big as Express JS?

When I got into web dev about 1.5 years ago and started doing Node JS projects, it seemed that Koa was going to the new top dog. It seemed like everyone was migrating from Express to Koa, because, one it's promised based... and that's it. I don't what more it offers.But (to me), it seems like the modern JavaScript always praises promises over callbacks, yet, I still see projects using Express.BONUS: What server framework (if that's the right word) do you guys use?Also checkout: koa-vs-express
