I don’t use these terms because they have undesirable connotations and are unfamiliar to most English speakers. Calling morality as it is actually reasoned about in the real world “descriptive” only makes sense as a way of emphasizing that you seek to describe something as opposed to endorsing it. OK for philosophers (and folks working on CEV, perhaps), not so much for everyone else.
