That's cool that you can do that. I worry though that the level of complexity required to set that sort of thing up will act as a hurdle for many that might want to use that feature.
If the node graph is saved in the document (?) perhaps there exists then a "template" (empty document) where the node graph is already set up for palette dithering. That would make it easy to onboard for new users.
