Overworld Shadows

Has there been any talk of adding shadows to player and NPC overworld sprites? Recently I added this Overworld Shadow script by KleinStudio and it pretty much worked like a charm on Reborn. There are some rare instances were a shadow appears were it isn’t supposed to be/lags, but that has to do with how I haven’t limited the shadow events, and is something that could probably be fixed by someone who knows something more about coding. Couldn’t the same thing be done/tried in Insurgence?
