I don't read it as a call-for-action-by-others at all. It seems that with this post and the previous one lukeprog is responsibly trying to verify that a problem exists, presumably as a necessary prologue to working on the problem or at least trying to strategize about how one might go about working on it. And I also don't agree that it's generally unproductive to point out the existence of problems without simultaneously offering suggestions about how to solve them: sometimes the first step really is admitting (or realizing, or verifying) you have a problem.
