^ Canon is more about story than gameplay elements.
Keeping in mind the idea that Tropes Are Flexible, you could make a case that the first example is in the ballpark of Borrowing from the Sister Series. Instead of another series by the same creator, the borrowed element comes from a later work in the same series that is added into the remake of an earlier work. IMO that's close enough in spirit.
I was wondering if there was a trope for this, as something I did always think of is how Xenoblade Chronicles 1's Nintendo Switch remake did something like this.
- Xenoblade Chronicles 2 introduced a meter of how much longer an enemy would have a Break/Topple/etc status effect on it, showing the player how much time was left before it wore off. This wasn't present in the first game, but was added to the UI when it got remade.
- Similarly, I saw this used in a JoJo's Bizarre Adventure fanfic, where a later installment started referring to Stand names in brackets, which was retained for an interquel that was made.
