A few days ago, I was browsing through the Oxford Handbook of Personality Assessment: It doesn't have a chapter on MBTI. It's only mentioned a few times, but that was it. Keirsey is not mentioned at all.
The Oxford handbooks generally have a very good reputation, regardless of discipline, and even the worst of them are still good. That confirmed my suspicions about these models (especially Keirsey), namely, that they headed for the market because their work were not recognized within the academic community.
What's your opinion?
