I think the title is a little bit misleading. The moment you can drop support for browser versions is pretty dependent on the requirements of your client, and your visitors. 7% for users with IE8 or lower is a pretty tech-savvy crowd, many developers might not have the luxury of dropping support for IE8 because many of their visitors still use that browser.

Agreed. There's still a very significant portion of China using IE6, for example. If you've got an international focus on non-developers, it's not really even close to feasible to drop IE6-7.
