Interesting.
So is there a generalized best practice?

Typically I want these retained, but that doesn't work, at least in non-ARC code, because CF types aren't recognised as being retainable. So I declare them as 'assign' but usually leave a comment that it's really copied, CFRetain'd, etc. (and of course I have to write the setter methods myself to make that true). Is that my only option? It would be nice if this were better supported.
