I see that various mandatory steps in chromestatus
(privacy,security,enterprise,debuggability,testing) seems to be
unstarted. It is possible they were made mandatory after you create the
entry, but it would be good if you could get them started now at least.
Also, it's unfortunate that TAG and standards positions requests have
not resulted in anything, but that is hardly your fault. There were some
questions in the WebKit request. Is all that ok now?

Specification
https://github.com/MicrosoftEdge/MSEdgeExplainers/blob/main/PointerEventDeviceId/explainer.md
Summary
As devices with advanced pen input capabilities are becoming
increasingly prevalent, it is important that the web platform
continues to evolve to fully support these advanced features in
order to unlock rich experiences for both end users and
developers. One such advancement is the ability for a device's
digitizer to recognize more than one pen device interacting with
it simultaneously. This feature is an extension to the
PointerEvent interface to include a new attribute, deviceId, that
represents a session-persistent, document isolated, unique
identifier that a developer can reliably use to identify
individual pens interacting with the page.

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
Debuggability
Will this feature be supported on all six Blink platforms
(Windows, Mac, Linux, Chrome OS, Android, and Android WebView)?
No
Is this feature fully tested by web-platform-tests
<https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>?
No. However, there are web tests in Chromium that test
PointerEventInit with this feature.

PointerEventDeviceId
Finch feature name
Non-finch justification
Edge origin trials successfully underway.
Any Origin Trial feedback you can share?
Absolutely, the feature has been working well. Our partners (Microsoft
Whiteboard) have enabled the feature that is dependent on this API for
their general audience! We did not receive any constructive feedback.
This API is being used by them on Microsoft Surface Hub devices, which
support multi-pen inking.
Requires code in //chrome?
False
Measurement
PointerEventDeviceId use counter implemented.
Availability expectation
Initially available on Chromium browsers on Windows.
Out of curiosity, are there limitations on other platforms that
prevent supporting this feature?
We haven't been able to get our hands on hardware that supports other
platforms in addition to multi pen inking in order to implement and
appropriately test this feature. We welcome any sponsors for
implementing and testing this, especially on Linux/Android.
Adoption expectation
Feature is used by specific partner(s) to provide functionality
immediately upon launch.
Adoption plan
This feature has been through origin trials on Edge. It is being
used by partners that provide features on devices with multi pen
support.
Non-OSS dependencies
/Does the feature depend on any code or APIs outside the Chromium
open source repository and its open-source dependencies to function?/
Operating system API's are used to obtain the device id, and are
necessary for this feature to function. Please see the security
questionnaire in the TAG review on security and privacy concerns
related to the use of these APIs.

Anticipated spec changes
/Open questions about a feature may be a source of future web
compat or interop issues. Please list open issues (e.g. links to
known github issues in the project for the feature specification)
whose resolution may introduce web compat/interop risk (e.g.,
changing to naming or structure of the API in a
non-backward-compatible way)./

web compat/interop risk.
