As someone who does like TRoS, I just feel like some changes miss the original executed meaning of specific things/plot points/whatever and/or undermine those.
That’s the point of a fanedit though… to change the meaning of specific things and plot points to the editor’s executed meaning.
But as I stated, the scene with the children establishes a connection with the galaxy in just TRoS (as if it were a standalone movie and not a sequel) and raises the stakes. It’s more personal and thus meaningful than just reinforcing TLJ. The heroes are fighting for the future of the galaxy, which the children symbolize.
