I'm not sure about using them for list scrolling, but they are definitely interesting effects that would be great to show new elements getting added to a list (e.g. of notifications for example).
Yeah, there sure is a place for fx like these - but it's applied in the wrong place here. Scrolling lists are a nightmare to read even without such effects. A place where I could imagine myself using it is as an intro/outro effect, drawing a user's attention to a list.
