I refuse to accept them as legendaries. They hold no value (except latios and latias) and I refer to them as sub-legendaries because they are more or less of a filler to get more "legendary" pokemon in one game.

Yes, they are legendaries on the exterior, but they really miss the point of what getting a legendary was about, having a good backstory and being hard as hell to get. Like Mewtwo or Kyogre.
