Should I drop bindonce or Angular 1.3 one-time binding if I use collection-repeat?

While using this syntax in a collection-repeat:

<ion-item collection-repeat="item in ::items track by"

I get an empty list. (note the :: syntax from Angular 1.3)

Should I stop using one-time binding when using collection-repeat?
Collection-repeat allows to drastically reduce the DOM loaded at one time.
So shouldn’t I worry about not using ont-time binding?
