Like the comics, if the writers of the show decide otherwise then there's nothing it can do.

You could still keep the thing of Savitar not hating Iris, it wouldn't change any of the interactions with the team prior to the identity reveal honestly. But it still makes no sense that killing Iris would allow Eddie to live.

It is canon to the show though. It isn't like the main DC comics where it is seperate. It takes place in the Arrowverse. (In Pre-Flashpoint continuity)
