Any possibility for the developers to add an update to let players change their current world settings without having to start over?

I don't mean by changing the map size from default to big, but small changes like: turn on/off frog rain, disease, wildfires, forest petrification & the frequency of meteors

Would it be possible for this to be an update in the future? I just don't understand why players have to start a new world if they wish to change the frequency of a certain resource.
