Well, based on BOTW happening at the end of all timelines, that means it occurs after Twilight Princess, Ganondorf's last appearance, and so its safe to assume this incarnation of Ganon didn't last afterall.

(Oh and there's also Four Swords Adventures in that timeline after TP, different Ganon there too.)

On the other side of the ring, Salem is literally immortal as long as the Gods wish so, and there seem to be no caveats to this.

In short, Ganondorf has canonically been killed, Salem seemingly cannot be by any means.
