World Border manipulation via commands for Bedrock Edition

I have been wishing for the /worldborder command to come to Bedrock edition and I want it to work the same way it does in Java edition, you know like how when a player goes outside the world border in Survival mode they take damage? I want that in Bedrock edition and I want the command to work like it does in Java. Or is the command in the game but is an experimental feature, or is the Bedrock team working on the command as I speak?
