I know LocalStorage is used in a lot of mobile-specific Web content  
that targets WebKit-based browsers. I also expect there are mainstream  
sites using LocalStorage at least as an alternative when available,  
given that it's in the latest version of nearly every brrowser.

If you think changing LocalStorage incompatibly "definitely wouldn't  
break the web" then I'd like to see some data.
