I'm fairly certain that most functions in Go don't take a context. There are tons of helper functions like those in the fmt or strings package that don't, for instance.

Oh and let’s not forget about… basic IO. In order to apply cancelation to IO you have to create a new goroutine, wait for the cancelation, and then interrupt the io. Oh, and you need to remember to not leak that goroutine.

There are tons of helper functions in the standard library, but the standard library is quite small compared to all Go code in existence. You also can't really change the standard library, so it's unlikely you'd suddenly start needing a context in fmt.Sprintf
