This has been requested many times before.  Search the archives for 
parent selectors and the :matches() proposal.  IIRC, such proposals get 
rejected because it doesn't fit the CSS processing model and also 
performance issues.

:not() can only contain a simple selector.  In other words, it cannot 
contain any combinators.

These are not:
   :not(foo bar)
