Richard Wackerbarth is doing the work on this branch. It is my expectation that after we do the next release this will be used as the next official MarlinDev environment with the intention that it will be promoted to Release Candidate status. (Mostly, I'm just trying to say, this isn't wasted effort on your part.)

My suggestion is go to https://github.com/MarlinFirmware/Ma...3Aupdated-desc and start a thread asking for assistance. Please be sure to explain why you are trying to use the branch and that you were requested to use it and ask for assistance at MarlinDev. The problem is I'm just starting to get my head around the new organization myself. I'll help you with what I can, but the changes that it takes to clean up the code are extensive. You will get better and quicker help at MarlinDev.
