Being a volunteer doesn't mean to not have any responsibility.

It's grossly unfair to insinuate that being a volunteer is associated with laziness or a lack of responsibility.

There are a myriad of things that we as packagers do that are completely silent to the surrounding automation and for which most people are never even aware.  Working with upstream development teams, for example, filing bugs on their systems.  What Fedora sees as a patch or a version bump to a package may be the result of hours of thankless work on the part of the volunteer packager.   

If you want to find a way to automate notification that a maintainer is unresponsive after a reasonably period, fine.   Obsoleting their packages is just wrong however.

In my opinion, "irritating" is when a maintainer doesn't reply to bugs that users fill in Bugzilla. If they can't found enough time to reply or change state of any bug in a six months period, than maybe it is better someone else take care of their package.
