If you are actually happy with the direction the Superman books have taken, you need to let your posts know about this
I understand you are frustrated, but you are being overly pessimistic. It is not abundantly clear that everything Morrison did is gone. It is not abundantly clear that Secret Origins is the only thing that counts in regards to Superman's early years. If that were the case, then they wouldn't have tweaked the look of Jor-El, Lara and Kal-El's ship to incorporate elements of the New 52 version. They wouldn't have gone out of their way to point out that the Kents were still dead like they were in the New 52.
The only thing that's clear is that Secret Origin is the spine they are using for this latest version of Superman's origin. Not the entire body. The reason for that is pretty simple: Johns & Frank's story incorporates elements from virtually all the various incarnations of Superman over the decades, which is a pretty clear indication that they aren't dumping all of Morrison's stuff. However, not all of it will fit. Everything from the Pre-Crisis Superman isn't there. Only some of it. Post-Crisis Superman isn't all there either. Only the broad strokes.
No one version of Superman is 100% represented here. He's an amalgamation of all of them, and his history was left deliberately vague for a reason. Creators are now free to pick and choose from EVERYTHING moving forward. If one thing contradicts another thing, it doesn't really matter right now because the timestream has been nuked by our beloved glowing blue nudist. Everything is up for grabs right now. Head canon is DC's new policy because it gives creators and readers the most freedom.
Now, you have a choice moving forward. You can be optimistic and approach the current situation like Superman would or you can approach it with pessimism like Batman would. One of those options makes you grumpy and unhappy. The other brings you joy and happiness. I know which one I have chosen. You may think me foolish for looking for the best in things, but that's only because I try to do what Superman would do in a situation. What about you?
