It was designed with as many restrictions as I could think of (everything 
which was not part of the need to add it at all):

 http://www.cmake.org/gitweb?p=cmake.git;a=commitdiff;h=370bf554

The restrictions are there because they are easy to lift later when a need 
arises without breaking user code. It also means that design considerations 
which were not known or understood two years ago can be considered in 
designing new interfaces.

Do you have a need for ALIAS IMPORTED libraries? Can you describe it?

Thanks,

Steve.
