Chromecast to Add Support for Tap Gestures (Is This for Gaming?)

A recent code change request on the Chromium repositories talks about adding support for tap gestures in Chromecast. Considering the fact that we have news about a new version of Chromecast with Bluetooth support, is this a move to make Chromecast a gaming platform? I mean, it is no secret that Google is interested in making Chromecast a gaming platform too.

The Code

The code talks about adding gesture support:

[Chromecast] Chromecast support for tap gestures

– The gesture detection is attached to the root window and handles
tap, tap down, long tap, and long press events. A custom handler
(CastGestureHandler) can be installed or removed to handle
these events.
– Renames CastSideSwipeGestureHandlerInterface/CastBackGestureDispatcher
to generalise them.

I cannot think of any other use for tap gestures on the Chromecast app, other than gaming. Google could stream the game over WiFi and use phone’s Bluetooth for controls. That’s what I am imagining.

The only mention on gestures in connection with Chromecast is in accessibility settings. However, accessibility is not mentioned anywhere in the code change request. So, it is safe to assume that this is indeed for game controls.
