Please do not under estimate the seriousness of this issue.

Imagine spending 100's of hours on your world only to find that when the world file reaches 900mb the world can no longer be played.

Well that's what happens in Bedrock. Why even play Bedrock Edition if you want to create a large world? In fact, in terms of massive buildings my world is all but empty, but because I went out a few thousand chunks to find rare biomes I can no longer play the world because Minecraft insists I've no more storage.

It seems Mojang have known about this problem for a long time, but have not even acknowledged it.

This issue will be posted EVERY SINGLE DAY until somebody responds.
