GFZ is kind of an animal to handle! Everyone says they're unhappy with it and everybody wants to get their finger in the pie, but basically every remake of its textures and flats ends up looking like garbage by comparison for some reason. It is the GFZ curse. So, instead, minor tweaks to make things objectively better without making things look too different (and therefore fall victim to the GFZ curse) is the way to go.
