I agree this one needs a spec clarification as changing the implementation would be an incompatible change leading to the methods apparently failing for cases where they didn't previously fail.  I don't think it will work to just add an apiNote, it needs to normative. Also the descriptions of the return value say that the method fails (which can be interpreted to mean return false) when the file system doesn't support the permission.
