At the risk of sounding tautological:
To the extent that you’re talking about your Hosted Game, Hosted Games (a different company than Choice of Games) will host your game.
To the extent that a back button goes against Choice of Games’ design philosophy, Choice of Games won’t implement a back button. BTW, just glancing through the other threads you cite–“numerous occasions where I’ve selected an option, only to find the author had loaded it with numerous unforseen consequences, which I didn’t wish to accept” also goes against our design philosophy, so it’s not a problem that needs fixing in Choice of Games releases.
