It wouldn't be a bad idea to enlist CZ to do some changes, if needed. After all he stills gets his fee, and it would benefit him if that fee is higher in price due to development.
He's planning on incorporating a lot of things from his other project, so I'm not sure if current course is prudent.
I was wondering about that as well. CZ has stated that he's not abandoned BBR and will be incorporating changes in the future. This "takeover" seems premature.
