So I have an update video coming out where I have gone into the DSM source code and figured out what happened with WDDA.
I found this file which I believe to be the document used to communicate WDDA requirements from WD to Synology.

The reason that I believe this is actually the document from western digital is I found the same document on a Japanese NAS manufacture here:
From this we can see that it looks like Synology implemented WDDA correctly.
