If we had such an 'obsolete' tag, it would be nice to add color coding to them (make the background pink or something) so you can tell when you're looking at it that it is probably out of date.

I think the above is a huge problem encountered when using the Drupal.org search functionality. And this is a problem that will only get worse over time. There is a lot of 'cruft' on drupal.org that only relates to unsupported releases, and has no application to current releases.

I wonder if it would be beneficial to make an 'archive' or 'obsolete' flag available to documentation team members, which can be applied to all content on Drupal.org, then have those nodes removed from search by default...
