Agree with Raymond. It should be made clear along with the pointer that the pointed PEP could be outdated. Maybe simply writing
(original PEP: :pep:`42`)
is enough? The word 'original' implicitely stating that things could have changed?

To me the most important aspect is not about having details (still, it's important). Instead it is to get an (even partial or obscure) answer to "why", that often simply misses in the official docs. This answer is necessary to interpret the "what" and/or "how". Nobody can properly understand a feature description without knowing its purpose. In the best case, the reader will guess it, in he worst, he will guess wrong. Explicit is better than... also for docs!
There is also a pedagogical aspect that I find even more relevant. An unexperienced programmer or pythonist should at least be able to figure out vaguely what this or that feature is about. No doubt this is very difficult to achieve -- especially for experts! I imagine a 2-stage "why" introduction to every feature description in the docs: the first one targeted to non-specialists, the second one more technical. (I'm sure that the first one would also sometimes help specialists.)
The pedagogical one must be worded by, or reviewed by, or written in colloboration with, "tutors" that are able to imagine where/how/why newbies may stuck. It needs not beeing long -- sometimes a few words may be enough. (But it will sometimes be the hardest part ;-). It would also benefit from newbie feedback. I wonder whether this task could be partially delegated to the python-tutor mailing list activists.
PS: If ever, I volonteer to take part to this kind of task -- for the french version. [Have been technical trainer (in automation) in a previous life.]
