Your assesment is correct.
I have a version that is nearly complete for Windows(for other platforms 
I have't done anything). But to have RTTI on all platforms, that is 
still delphi compatible is not possible(at least for me), due to the 
nature of some architetures / calling conventions.
When I have some free time(after the tests for this semester) I will 
probably be able to post a patch.
