We've been through this before - it's an apples and oranges thing. Degrees (indeed all level 6 quals) must involve an element of original research. That's not really appropriate for pilot qualification. The pilot quals are closer to Professional qualifications like accountants, doctors and lawyers, demonstrating absolute mastery of a specific body of knowledge and the ability that expertise accurately and reliably in a real-world situation. Note that there are degrees in accountancy, medicine and law, but you can only achieve the professional status through the professional pupilage and exams (and it can be done with or without the degrees). Heck, even engineering isn't just a matter of having the degree - a Professional Engineer (whether as a C.Eng, the European Eur Ing or the colonial PE registration) is more than just a degree.
