Comment (by titsmaker):

 Just ran across an issue with WooCommerce widget's CSS loading on every
 page. Some function to check if widget is active on the current page would
 help a lot to load CSS conditionally thus improving WordPress performance.
 There are some solutions now but they are not easy enough to implement.
 Maybe it would make sense to add a performance focus to this ticket?
