My question was not a criticism, but a genuine question, mixed with 
pleasant surprise that possibly my information about them not being 
supported was not current any longer.

Sounds good enough to me.

OK.

What is missing then?  Just the automatic search of framework 
subdirectories for headers and shared libs?

I am not imagining anything, I am simply asking what the status is.  
From what I hear the status is:

- frameworks work just as expected
- the only exception is automatic searching for headers and shared libs 
inside framework directories
- the workaround for that part is symbolic links in the libs and 
include directories.

Not really necessary from my point of view, but nice to have.

Treating a framework like a bundle and loading it dynamically?

Thanks for all the info!
