Now that you have removed the debugging symbols of the Bedrock Dedicated Server, please publish at least the preview protocol docs. This does not seem to be an effort as the protocol docs are generated automatically so please do the community this favor. Please publish the protocol documentation as soon as possible after transmission to the partnered servers and add preview support. I would greatly appreciate it if you would comply with my request.

The Bedrock protocol documentation for the Preview version 1.21.10.22 
(r21u1, Network Protocol Version 704) is missing from the GitHub repository: https://github.com/Mojang/bedrock-protocol-docs.
