I have just realized that the platform profile module does not check if
the profile the user wants to set is supported by the handler. As I've
mentioned in my other email, I think that should be checked. You could return
EOPNOTSUPP there (in the platform profile module). After reading the explanation
why you want to use EOPNOTSUPP, I believe it makes sense and it's fine.
