The end of Endgame should have been Admiral Janeway learning the lesson about her crew that she did actually make in the actual episode, and then that should have been it. She could even still sacrifice herself to save them. None of this having their cake and eating it too bull.
Also this way, any scenes set in the future would actually be scenes from the future.
That would create temporal paradox, Captain Janeway would know about her future actions, so would have no need to eventually travel back in time, once she finally reached the Alpha quadrant and is promoted to Admiral.
But if she never traveled back in time, her past actions would never technically have happened.
