This is only true today because :hover only works on some elements in IE. 
Dropdown menus, methods to display more information about objects etc have 
already been written for browsers supporting :hover on all elements.

For example: http://www.meyerweb.com/eric/css/edge/menus/demo.html

These forms of display have previously only been possible with JavaScript 
etc, the use of :hover is an important tool for a cleaner web.
