I don't see any great need to keep the pages. They can be undeleted if anyone wants to know what they said (I'm sure most admins would be happy to oblige, barring the usual concerns about copyright and libel). I think the reasons why we delete articles even though they may contain interesting information apply just as well to talk pages.
Keeping them carries the risk that they may contain useful information that may be helpful to someone wanting to recreate the page. ;-)
