Yes, but this will be difficult to determine. Lots of users are running "historical" servers. We can probably remove some entries but remember that in old forum posts we referred to FAQ # and people are still finding those posts.
One way to maintain the old urls would be start versioning the new documentation. Thus, the 3.x release of phpmyadmin would have its documentation living at http://www.phpmyadmin.net/documentation/3/ or http://www.phpmyadmin.net/faq/3/en/ or http://www.phpmyadmin.net/changelog/3/en/. The mysql documentation has been written this way - http://dev.mysql.com/doc/refman/5.0/en/index.html. Apache documentation uses similar url schema - http://httpd.apache.org/docs/2.2/ or http://httpd.apache.org/docs/1.3/
A good reference on (somewhat) related topic is w3.orgs "Cool URIs don't change" http://www.w3.org/Provider/Style/URI.
