What case?

The spec says that media types are mutually exclusive:

"Media types are mutually exclusive in the sense that a user agent can  
only support one media type when rendering a document."

I don't think it is feasible to change that. You can use  
media="screen,projection" for a stylesheet with general styles, once you  
start catering for the projection case. Or just leave it at 'all' or not  
specified, for the stylesheet with general styles.
