I'd say that in this case for most people it is not valuable to read the history of the argument but rather an up to date summary of it - the originally made argument is worth reading if and only if it's the best way to make it, no parts of it have been refuted and no one has found a way to state the same thing better.
Instead of listening to what, for example, Kant had to say originally, the proper resource should be a "steelman Kantian" position which omits anything that has valid refutations, which changes anything which has been disputed because of some nuance by integrating whatever fixes and corrections can be made as a result of the counter-counter-arguments, and prepare a coherent position which is solid even in the face of all the counterarguments which have been said in the centuries afterwards, a "what would Kant say after reading every Kant-influenced philosopher" statement.
If some argument made by Aristotle still stands, then readers of philosophy should not be offered the counterarguments without an immediate reference to the counter-counter-arguments that dismiss them.
And if some argument made by Aristotle is not perfect, then readers of philosophy should not be presented with that argument without the counterarguments; or (as I said above) in a corrected and augmented form, dismissing and ignoring the flawed original - the original is relevant only as a historical footnote of how the truth was found, but is not really relevant to the truth itself.
A product of philosophy should be actual conclusions - okay, out of all the Aristotle's works, which parts are considered settled truth, and which parts are part of an ongoing debate? And if so, what is the current, state of art position in that debate, what are the best irreconcilable arguments on both sides?
