Remember a few years ago Mark Millar was hired to oversee Fox's "cinematic universe" for X-Men and Fantastic 4 movies.... Did he ever actually do anything? After that news of him getting that job I can't recall ever hearing from him again about it.
While I do think you should chill a little and check Logan out first (if you hate it you hate it, if you love it you love it) and it's probably best to just think of it as a What If and try enjoy it for what it is, or at least that's what I did. As if not yes I do agree with your point, who cares whatever happens in "X-Men: Supernova" (or whatever it will be called) when they're all just gonna die anyway. Well, I mean everyone dies at some point, but in such a pointless, meaningless way, in renders the whole point of the X-Men and Xavier's dream for mutantkind pointless to watch IMO
