It turns out, that may just have been the start, as Google revealed yesterday that it is planning on fully deprecating that permission in a future Android release, replacing it entirely with Q's new bubbles-style notifications.

Google Search and Assistant are getting new instructional chops and deeper app/service integration

As part of the Google I/O brouhaha, Google is announcing a handful of changes related to Search and the Assistant, all of which should help you get to the information you need faster — albeit in slightly different ways. First, Search will soon support a so-called "HowTo" markup schema for web developers and video makers, which will allow for their content to appear as results in related how-to queries. Second, Google is expanding App Actions to more deeply integrate a few new types of services including health, finance, and ride-sharing into the Assistant.
