I have a DO-based application which uses a Class object as a root
proxy under 10.4- it works as expected. Objective-C 2.0 seems to have
broken this option because Class no longer responds to -
encodeWithCoder:.
I am not able to think of a reason for this regression, but perhaps
the new dynamic nature of Classes prevents my use-case.
Is this a genuine regression or should I have never relied on passing
Classes as root proxies?
