There have been several such changes that have already made it in, I don’t see how this is anything but an improvement.
The inclusion of the deleted scene is probably the most obvious example, though I’d argue that if the theatrical relase had been structured this way (Hosnian destruction and Han’s death at the same time), that scene would never have been cut and would be where it’s been placed in the edit, so in a way it is within the scope of the edit. Even though it also isn’t.
