It's a nobel effort and with good motivation behind it. But as with another recent plugin that was introduced to notify users of security related plugin updates the major problem with these types of plugins is that people don't keep their plugins updated so how can we expect them to install a plugin like this and actually use it? The short answer is they won't. It's a major problem that the community needs to find a way to address. Users aren't updating even when all they need to do is click a link to do so.
