A note on timing: the OT expires in M140, which means that users
who upgrade to M141 (scheduled to go out next week) will no
longer have access to the feature. November 11th is the day after
the hard-coded expiration date of Nov 10th for all users (i.e.,
folks who haven't upgraded past 140). That means your partners
will need to deploy the newly minted extension token before 141
goes out to avoid any disruption. So if you click on that button
I can approve and maybe they can hit that deadline.
A small correction here: the feature will continue to work for any
version where the feature exists (so, M141+) until the hard-coded
Nov 11th expiration date. So less stress for partners, but they
will want to deploy the updated token before then.

Hello blink-dev,
Our team requests two changes for the existing Permission
Element (PEPC) Origin Trial.
<https://chromestatus.com/feature/5125006551416832>
1.
A timeline extensionfor three milestones, to M143.
2.
An increase in the page load limitfrom 0.5% to ~5% of Chrome
page loads.
The current Origin Trial for PEPC is set to expire with M140
(Nov 11th), while we are targeting the launch of the
standardized <geolocation> API
<https://github.com/WICG/PEPC/blob/main/geolocation_explainer.md>inM143
and preparing a new OT for a <usermedia> API
<https://github.com/WICG/PEPC/blob/main/usermedia_element.md>.
The extension is needed to prevent a disruption for our
partners, and the page load increase is critical for new
experimentation and for ensuring a smooth, validated path to a
full launch.
Rationale for Extension & Page Load Increase
The PEPC API is already providing significant, measurable user
benefits
1.
Unlocking Value and De-risking the Launch:
*
Preventing Partner Disruption:For example, in a
high-traffic web service, users who specifically clicked
'Use precise location' previously encountered barriers
to changing their settings if they had blocked location
permissions. PEPC resolved this, leading to
approximately +17pp and +36pp increases in successfully
adjusting settings on Desktop and Mobile, respectively.”
Extending the trial ensures that partners like Zoom,
Cisco, Zaplmoves, and OLX BR,Meet, Searchand others do
not lose this functionality until we roll this change
out. (see some use cases here
<https://developer.chrome.com/blog/rethinking-web-permissions>)
*
Validating at Scale:An increased page load limit allows
our high-traffic partners to scale their successful
implementations beyond the current OT cap. This delivers
the feature's proven benefits to a wider audience sooner
and, critically, allows us to validate that the positive
results from a small experiment carry over at a larger
scale, mitigating risks before the full M143 launch.
2.
Enabling New, High-Impact Experimentation: We need to
increase the page load limit to validate PEPC's integration
with the upcoming Approximate Location
<https://github.com/explainers-by-googlers/approximate-geolocation>feature.
*
PEPC provides a natural, user-initiated entry point for
managing location granularity (e.g., changing from
approximate to precise and vice versa).
*
To get this right, we need to test several UI variations
(different button treatments and prompts) for this new
user flow.
*
A higher page load limit is necessary to gather
statistically significant data across these experimental
arms, ensuring we can differentiate user behavior and
build the best possible experience before launch.
3.
New Experimentation Plan: Based on valuable feedback from
other browser vendors, we are splitting the generic
<permission> element into capability-specific elements. This
OT extension provides a bridge to that future:
*
Geolocation: The learnings from the current OT
(including the Approximate Location experiments) will
directly inform the launch of the new <geolocation>
element, targeted for M143.
*
User Media (Camera/Mic): We will create a new, separate
OT for <usermedia> to continue collaborative development
on its API shape after the current OT expires.
This plan ensures continuity for our partners while allowing us
to ship the most stable, consensus-driven solution. We
appreciate your consideration and welcome any questions.
Best regards,
Minh on behalf of the Chrome PEPC Team
