I see many folk on this forum say that the reason for adding extract at the end of the boil is to prevent scorching and caramelization and I don't doubt that that is a reason but might there be another reason that applies to even the most careful brewer and that is one that deals with the utilization of hops?
The lower the gravity of the wort during the 60 minute boil time means the greater the utilization of the hops,doesn't it and so if there is no good reason to increase the sugar content of the boil - and there would seem to be none because the LME or the DME do not need to be boiled in order to break down the sugars in those malts - then the obvious benefit is that more of the hop acids will be isomerized if any LME or DME is added at flameout. Why is this reason rarely given?
