I tend to worry about such centralized and automated efforts. I am a lowly user, so the only way it would affect me would be if it removed a plug-in that I already use (and not all of us use just the newest, though updating old ones when possible is a routine for me). Regarding the above, absolutely it should not just identify that there is a problem and not let the developer know what and if possible how to fix; I could see that discouraging people from submitting a plug-in, and consequently from even developing one.
