Anecdotally, I know a few people who spent decades working on and/or teaching middle eastern music in conservatories abroad, and they struggle greatly to find music departments in the US who will hire them. A problem I've seen firsthand is that there are a lot of senior professors who teach it hand wavy versions of it filtered through whatever books Euro orientalists wrote mid century and are threatened at the prospect of someone coming in there who has studied and practiced it for years in places where it's more of a living art form cutting into their position of expertise.

Where this ties in to your point is that part of the reason they really don't want experts is that they rarely have someone whose job it is to teach middle eastern music. They might have a guitar teacher with some experience with oud, a flute teacher who can passably play ney (usually with awful intonation), etc. For most schools, these other types of music are "add-ons" that they have their existing faculty teach.
