What qualifies as "active development" on drupal.org? The D7 JW Player module claims to be "Actively maintained" and "Under active development", and yet hasn't had a commit in 30 weeks.  

The page for "Actively maintained" implies that the only required qualification for that status is that bug reports are "looked at".  That seems pretty minimal to me.  What about the requirements for being considered "under active development"?  Is there really any requirement or can any module be listed as such if its maintainers say it is?
If you have edit permissions on a project, you see that it is a vocabulary:



The link is to Maintenance of your project.  In other words, it is essentially an honor system that the project creator sets.  Unfortunately, developer loses interest in a project they also tend to lose interest in maintaining the webpages and documentation.
