I'm sure for the same reasons you'd want to keep Mikal. Who hasn't a penchant to hire a Middle Eastern 'specialist' with cultural understandings of the esoteric Druze, the Yehudim Yisraelim, and one who has roots in Hinduism?
While there is no one person that I wish had not joined the crew (and instead, led a different life), I will admit that there were some members that could not stay. I've taken these as lessons learned, of course.
