The WHATWG DOM spec was spun out of W3C DOM level 3. Neither document was ever associated with or aligned to any version of HTML, though the WHATWG did try something like that and backed off when all the browser vendors refused to give them the time of day. Now the WHATWG document is largely the document of record and W3Cs DOM level 4 is largely a snapshot of the WHATWG document.
None of this is either confusing or a mystery. It’s all out there in the open and the people who maintain these documents respond to email. I typically avoid talking about the DOM online because many developers aren’t aware of what it is and are less aware of its history and sometimes people get sensitive about it.
