    I see the point that creating non installed system L&F may not have 
many sense.

    One more use case that should be considered is using the 
createLookAndFeel(className) method with custom L&Fs.

    For example someone can have a list with L&F class names which 
includes both system and custom L&F.
    Using a class name he wants to check if the given L&F is supported. 
Does he need to install the custom L&F first?
    If no, he will need to handle L&Fs differently using 
UIManager.createLookAndFeel(className) for system L&Fs and reflection 
for custom.

   Thanks,
   Alexandr.
