Guess it has been removed for a reason, don't think it's useful anymore, if you want to migrate from Java to bedrock here's a little howto:

• Download your java map
• Open it with amulet_app.exe (you can find the open source project it's written in python)
• Go to Convert, convert it to bedrock (it will erase the selected bedrock map, you can generate one just for this)
• Save with Ctrl+S
• Upload the bedrock map directly to pocketmine
• You may have some errors with some extra metadata by amulet, it's only warning, nothing dangerous.
  - If you want to remove these warnings you can launch an extra conversion with this code https://gist.github.com/dadodasyra/1e031289fa50ba6c057022641bf5abd1
