@kevinhaig, Joel Birch submitted a ticket to have hoverIntent updated in WordPress.
http://core.trac.wordpress.org/ticket/23752
@esmi, I’m not a WordPress developer so I’m not sure what the page you linked to specifies/indicates (if it’s meant to be authoritative and/or needs to be updated), but per the ticket above I just learned that hoverIntent is bundled in the WordPress code!

@kevinhaig, I just updated hoverIntent (now r7).
– Backwards compatible.
– Supports event delegation.
– Supports handlerInOut, for parity with hover.
– Namespaced events, for better isolation.
Updated my site – http://bit.ly/hoverIntent
Pushed to GitHub – http://git.io/hoverIntent
I don’t have any more visibility into the use of hoverIntent than you do. I heard it was used in the admin pages of WordPress at one point (haven’t verified). Individual theme authors will likely need to update their themes.
