In Minecraft Preview, there should be a way to access normal Minecraft

In Minecraft Preview, I think there should be a way to access normal Minecraft What I mean by this is there should be an option to make a certain world normal Minecraft because some stuff don’t work in Minecraft Preview like mods and it would be a fun to play normal Minecraft, but I do think it should be limited like 3-5 maximum like you can’t activate the option all the time in all the worlds considering there is a limit , but if you decide to delete one of the world that you made into normal Minecraft, you should get one of you points back for example 1/3(before deleting 1 world) 2/3(after deleting) that’s all thank you reading
