Flash builder 4.7 not treating External linkage correctly

Question

Hi,
I am refactoring the project I am working to external link assets(flash assets), so I can load them on runtime.
This works in Flash builder 4.6 and you can observe a smaller .swf than if they are merged into code.
In FB 4.7 However it seems to ignore external linkage resulting in same size .swf as merged into code setting and I can run it fine without loading any external swf.
This seems to be yet another bug in FB 4.7 or its compiler, unless I am missing something.
Ps.
I am building the project with -frame parameter which seems to be the way to use a preloader with the new compiler:
see this post http://forums.adobe.com/message/4695625
The preloader is on frame 1, splash screens on frame 2 and 3 and rest of the project on frame 4.
Is this a known bug by any chance & or are there any ways around it.
I am using Asc2.0 Version 2.0.0 build 353448
Sincerely,
Ævar

here is a demo project set up similar to the main project having the problem.

If you adjust the linkage on the directory ./export/normal/swc to external, on the web project it makes absolutely no difference. While in FB 4.6 or using ant build it is smaller and requires a swf to be loaded at runtime.
That being said, I am now in the process of seeing if the method we are trying to use will actually work, since the iOS packager refuses to make a release build if it cannot find the class definitions at compile time. 
The idea is basically that the compiler uses external linkage to flash assets, and then depending if the device is retina or not it loads the appropriate swf.
