Another character could work in theory, but I wonder whether it would work  
in practice.

For example <meta name=viewport> was documented to support only comma, but  
thanks to silent error recovery authors ended up using and relying on  
semicolon:
http://lists.w3.org/Archives/Public/www-style/2011Oct/0652.html

I wonder whether reverse of it could happen with list of sources, e.g.  
unexpected comma parsed as invalid media query could end up delimiting  
sources in some implementations, and then we'll end up with worst of both  
worlds (both ambiguous comma and other unintuitive delimiter needed for  
web-compat).
