The goal is to keep potentially important information, for the same reason that we use version control.
I love history (I've listened to many history podcasts), including the history of mathematics. A common theme throughout the study of history is, "we know certain information used to exist, but now it's gone". For example, Stoic logic at one time was extremely popular & it was probably the most popular system around the Mediterranean & Persian areas. There's a lot we don't know about Stoic logic today, because what little is left is reconstructed from sparse sources. (Heck, we even have to reconstruct some of their *axioms*.) There are still debates about the meaning of Aristotle's modal logic; Rini has a very plausible interpretation, but there are also plausible yet different counter-interpretations. The problem is that there's so much that's lost that we have trouble understanding the context. And this is *Aristotle*, where have been many attempts to keep his works and yet we think we only have about 1/3 of them (See:
https://en.wikipedia.org/wiki/Lost_work ).
I don't think archiving the mailing list should squelch debate, especially since Google groups archives it anyway. I operate on the assumption that as soon as I post something publicly, it may live forever, so I'd better be prepared for that. If you want something to be private, a public mailing list is not a good place to send it :-).
