You can do this with mods, but it very quickly runs into file size problems, which in turn increases load times and the need for extra chunkloading if you want to do things in multiple dimensions (which can significantly increase the processing load). It's a nifty idea, but from a technical standpoint it's generally going to be better to add new content to existing dimensions.

The mods for Minecraft are not optimized well because they aren't given access to the source code, only a few hooks they've salvaged. That's the reason they have such terrible performance, it's not exactly because of their technical prowess. Java Minecraft, and mods in general (despite what people say) run poorly because they're optimized poorly. Adding gameplay content, as a rule of thumb, should be the thing that adds the least amount of extra needed storage, RAM, processing power, whatever. Minecraft textures are small and the music is... well, mp3 files.

My understanding is that the C# port is much faster and better with memory. While there is an almost endless stream of misinformation about how Java, C#, and .NET work, I was able to finally find the most accurate summary of Java vs Bedrock.

Anyway, if you chain one gameplay section with the next and limit the interaction between the segments to ways in which you know things won't get screwed up, I don't see why they can't just keep adding new dimensions forever. They might do that anyway, I mean they need to milk the cow they bought.
