I read matt ryer's excellent book "Go Blueprints" already. I know all that stuff. I use middlewares with complex logic, I write apps with hundreds of controllers, so with all due respect I'm not going to reinvent the wheel , each time I need to finish a project with tight deadlines.

I don't understand this Go community mindset which says that "nothing is needed but the std lib". My use case isn't Google's or anybody else's.

If the Go team wanted an idiomatic router or middleware stack well they should have provided fully featured ones in the standard lib. There are none. It means "user land".
