Are there plans for the Water System Plugin to be production ready or is it now defunct?

I know it’s labelled “Experimental” but for all the tutorials and livestreams done on it, some directly from the Unreal team themselves, it doesn’t seem anywhere near production ready. Since it came out almost 2 years ago now, should we just assume it’s a defunct system and find alternatives?

Perhaps the plan is to release a full feature version with UE5?
