Hi blink-dev,

User-agent client hint is currently ramping up to 100% of the stable 
release population, enabling default TOT on Android WebView. 

Best,
Victor

 I'm surprised you need a ramp-up for this. New APIs are generally safe 
 so we usually don't finch them. But if you'd rather do a finch roll-out 
 for 
 extra safety, I have no objection.

Hi blink-dev,

User-agent client hint is currently ramping up to 1% of the stable release 
population on Android WebView. 
New schedule timeline as follows:
1% ~ Aug 29, 2023
10% ~ Sep 12, 2023
TOT default ~ Sep 26, 2023

Thanks.

Best,
Victor

 Summary

 User-agent client hints (a set of `Sec-CH-UA-*`) aim to deprecate 
 and replace the User-Agent header to reduce the passive fingerprinting 
 surface we expose via HTTP requests. As we previously rolled-out 
 user-agent 
 client hints on Windows, Mac, Linux, Chrome OS and Android, we intend 
 to 
 proceed with shipping user-agent client hints on Android WebView. For 
 overridden user-agent strings, we only populate user-agent client 
 hints if 
 the overridden user-agent contains the default user-agent. In this 
 case, we 
 will only generate low-entropy user-agent client hints If users also 
 override the user-agent string through command-line.

 Risks
 Interoperability and Compatibility

 Introducing User-Agent client hints in itself won't affect any page 
 since it's purely opt-in features. It helps us to improve the 
 interoperability between Chrome and WebView. 

 Here is our proposed rollout plan in Chrome Stable channel 
 (Canary/Dev/Beta has been enabled 50%), with the understanding that if 
 we 
 discover concerning breakage or regressions via health metrics or bug 
 reports we will pause the rollout:

 Sep 5, 2023

 TOT Default (M117)

 Specification

 https://wicg.github.io/ua-client-hints/

 Summary

 User-agent client hints (a set of `Sec-CH-UA-*`) aim to deprecate and 
 replace the User-Agent header to reduce the passive fingerprinting surface 
 we expose via HTTP requests. As we previously rolled-out user-agent client 
 hints on Windows, Mac, Linux, Chrome OS and Android, we intend to proceed 
 with shipping user-agent client hints on Android WebView. For overridden 
 user-agent strings, we only populate user-agent client hints if the 
 overridden user-agent contains the default user-agent. In this case, we 
 will only generate low-entropy user-agent client hints If users also 
 override the user-agent string through command-line.

 TAG review status

 Risks
 Interoperability and Compatibility

 Introducing User-Agent client hints in itself won't affect any page 
 since it's purely opt-in features. It helps us to improve the 
 interoperability between Chrome and WebView. 

 Here is our proposed rollout plan in Chrome Stable channel 
 (Canary/Dev/Beta has been enabled 50%), with the understanding that if we 
 discover concerning breakage or regressions via health metrics or bug 
 reports we will pause the rollout:


 Stage

 Duration

 Date

 Stable 1% (M116+)

 M116 stable release is shipping to 100% (a best guess)

 Aug 22, 2023

 Stable 10% (M116+)

 ~2 weeks after previous stage

 Sep 5, 2023

 TOT Default (M117)

 ~2 weeks after previous stage

 Sep 19, 2023

 Stable 100% (M116=>M117)

 ~ Same business day as previous stage

 Sep 19, 2023

 Gecko: Non-harmful on User-Agent client hints (
 https://github.com/mozilla/standards-positions/issues/202).

 WebKit: No signals (
 https://github.com/WebKit/standards-positions/issues/70).

 Web developers: Mixed signals (https://crbug.com/1430051 
 ). We 
 know at least one site that uses user-agent client hints on Android 
 WebView..

 Debuggability

 No special DevTools support needed. The UA Client Hints headers will be 
 as debuggable as other request headers, through DevTools’ network tab.

 Will this feature be supported on all six Blink platforms (Windows, 
 Mac, Linux, Chrome OS, Android, and Android WebView)?

 Yes

 Notes: The existing flag UserAgentClientHint was already enabled for 
 other five platforms (Windows, Mac, Linux, Chrome OS and Android).

 Is this feature fully tested by web-platform-tests

2023-08-15 Thread Victor Tan 
Currently, we haven't confirmed the public plan for user-agent reduction on
WeView. We won't do user-agent reduction before completing roll-out
user-agent client hints.
