Well, we eliminated calamity Ganon, not Ganondorf (if I recall?). If Ganondorf died like that, which game did it occur in? Or is it implied that this death occurred before he became calamity Ganon, within the breath of the wild past? Breath of the Wild takes place like 10,000 years into the future after the initial calamity Ganon attack.

I am very much a fan of this theory and makes a good point in the forms that Calamity Ganon appeared in being mirrored from Wind Waker.

So a banished half-dead Ganondorf was the source of all the malice which took form as Clamity Ganon. I hope we explore further where this Ganondorf came from but it has its parallels to Twilight Princess with the spot in his stomach where he got executed.

It feels like Nintendo wants to merge all timelines into one with BotW 1+2

Makes sense to me. It's like Ganon, assuming that corpse is Ganon, is looking at Zelda to say "Did you think you were truly rid of me?!!".
