Specification
Summary
A collection of APIs that help developers target foldable and dual screen devices: Device Posture API and Viewport Segments Enumeration API.
This is an origin trial for both APIs because they are complimentary to each other, and we would like developers to use both when they design for foldable and dual screen devices. This is mostly a catch up with what native APIs on Android already offers for few years. The web APIs are available on all OSes however they light up on Android and Windows platforms only.
Each have their own chrome status entry : https://chromestatus.com/feature/5185813744975872 https://chromestatus.com/feature/5170498990243840

WebView application risks
Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications?
None
Goals for experimentation
Ongoing technical constraints
None
Debuggability
Yes, DevTools support has been added where developers can emulate on Android foldable, on Android dual screen and one Windows foldable. In this case the APIs are turned on and developers can see how their website react on the device (including visualizing the hinge).
Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?
Is this feature fully tested by web-platform-tests?

How many milestones are you requesting for the OT (whether it
starts in 125 or 126)?

Thanks - sounds good.
LGTM to experiment for 4 milestones (125 to 128 inclusive OR 126
to 129 inclusive).

One more thing, mind requesting reviews for Privacy, Security,
Debuggability in your chromestatus entry? Thanks
