Why is it that you're suddenly bringing this up when just a handful of posts ago you were talking about Stealth Rock? My beef was with your irrelevant arguments, not necessarily with the notion of removing Ho-oh's Suspect status. Honestly, I'm not even that strong a proponent of a Ho-oh Suspect test, nor could I give you any particularly convincing evidence that it "deserves" testing; I'm just looking at the fact that someone of relevance certainly thinks or thought that Ho-oh is a Suspect, be that Jumpman or Aeolus or whoever, and I have to believe that they based it on some of the "evidence" you're now demanding months later.
If anyone needs to be providing evidence, it's you, but I'm not even talking "Extensive Advanced Ho-oh Theorymon Analysis" evidence; just something that suggests a change in our knowledge, or in the metagame, that makes the conclusion we earlier arrived to either wrong or outdated. That's pretty much what happened with Mew, and I don't think it should be too difficult to do now without mentioning things that frankly make no sense like "but there's only one reason to test it!"
