Well yes, you could gather that, but also highlighting that what inspection boxes do in regards to F&R does not necessarily relate to the problems covered in the article because F&R has to work extremely quickly across the internet, often ruling out anything related how the box in the middle could see it and instead being about what endpoints can do independently via things like DPLPMTUD instead. The boxes do run into very interesting problems and knowledge space though, just more on the inverse of the problem at hand (how to properly act like a client receiving already fragmented data).
