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

Hi,
I think 4 milestones would be good (so M125-M129 or M126-M130). It
gives me ample time to reach out and partner with the various ISVs we
have in mind.
Thanks.

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

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 :

/Other signals/:
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
We would like developers to try the two APIs and provide feedback.
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)?
Yes
Is this feature fully tested by web-platform-tests
<https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>?
For now, no, we're in the process of adding Web Driver integration.
