I don't think it's that of a beneficial addition - the user should have the last say on which features of a save are enabled or disabled, and features that can make or break a save are saved in the BSON anyway.
When you open a save it already toggles newtonian gravity and deco mode to the correct settings (or at least it's supposed to). After that, a user should be allowed to change it to whatever they want. Elements don't interact with settings, they are just elements.
Also not sure if it's possible to code ... Element update functions can't access game settings so easily.
