There is a good argument for never using debuggers except for core development- Once finished your logs/metrics/events should be good enough to understand what is happening in an application. If debugging your application requires breakpoints you wont really be able to debug a live instance, and wont be able to easily signal off what is happening in the future.

That is a reasonable argument - but it was not made in the article and also does not preclude the use of breakpoints (see your except clause which covers a lot of ground).
