I think making a demo in ChoiceScript could help you decide. At the very least working on it will show you what works and what doesn't. There are novels from CoG that actually do have a save option. It could be that the authors simply chose to not include it in their work, aiming for "replayability" 🤔.

The thing is only demos have the save option available, and it's only provided by Dashingdon (Now CoGDemos), not CoG. The final game which is later released by HG or CoG never has it. I think it's because they think going back to a previous point isn't how these types of games are supposed to be played. Like, if you make the wrong choice you should just go along with ir because it's how it's meant to be. Like you said, for replayability purposes.
This is just my guess, of course, but if it's true, I disagree with them.
