Why doesn't drupal.org use "nicer" url's?

With path auto as a respected module that's recommended by every Drupal developer everywhere as a means to making websites make more sense to both users and web search engines, why oh why is drupal not using URL paths that make sense??

Instead of http://drupal.org/node/xxxxxx why don't we use properly named url's?

In the main handbook area, about one out of every 3 links lead to a mess of numbered nodes, and the other 2 lead to properly named pages.

If it is an issue related to performance, I don't see how we can't bring just the "important" or "public facing" pages, such as the Drupal Handbook's "Welcome README" in the About Drupal section (http://drupal.org/node/35172), into the current decade of proper urls.

Is it a matter of getting someone to type them in?
