I'm not particularly fond of this story -- I think its preamble is too long and meandering -- but why do you think this has something to do with 1882 vs 2020 audiences? And why do you think it's bad storycraft to leave the conclusion open-ended?
This kind of device is used to great success in modern fiction, such as Stephen King's (non-supernatural!)
short story "All that you love will be taken away", where the conclusion is not only open-ended, but also left to chance!
