The CM’s don’t generally post in the forums outside of bug reports and the official posts from what I’ve seen. From my understanding they do read all the topics, but do not comment unless needed. Even changes that I have seen that seems to have stemmed from forum posts, generally are not "acknowledged from them on the forums.
It would be nice to have acknowledgement that things are being considered, but emphasize that it is not guaranteed to occur, so don’t get our hopes up, but they generally don’t do that.
