remove historical EPEL information?

Hello, As part of th ewiki cleanup, some 'historical' pages will disappear, like https://fedoraproject.org/wiki/EPEL/SIG or https://fedoraproject.org/wiki/Extras/Schedule/EnterpriseExtras Is keeping this information in an historical section worth it? It would mean adding a page that references all the pages that are going to be removed such that interested people can save the information on the page before old pages are removed. -- Pat
