He didn't get a bitcoin core dev.  He got a friend of his who is knowledgable.  Considering that CryptoClub is a huge proponent of HZ and has been a part of that community from close to the beginning, I am presuming he got someone from that project to take a look.

He further promised a report (like he was/is an authority able to delegate like that) and that never happened.

His words have nothing to do with the project anyway and discussing his uninvited and perhaps presumptious talking points is an exercise in 'wheel spinning'.

My two cents.
