I think they are either too afraid of Dolohov, or too respectful, to gossip too terribly much. They did seem to think that Mr Nott was no great loss, which isn't surprising given how popular the Razzer was.

A lot of people spoke about how young Hydra, Padma, and Seamus are, but were careful to make a fuss about what an honour it was for them to be on the Council. I think they may believe that those three are to be your own personal squad of Council members, perhaps tasked to protect your life with their own now that Raz is gone.
