Autocompletion is a feature of the implementation. It could be provided by a
UA on top of a page without the page itself needing to request this feature.
i.e. it doesn't need to be specified in an API IMO.

Consent is implicit. By selecting contacts to share consent is given in the
same way as uploading a file works in the file picker. If I don't want to
share I don't click to share or click cancel when the contacts UI widget
appears.
