Per the market description, it resolves yes if there's a stable Chrome release in 2024 wherein Manifest V2 extensions are disabled by default for all users. While there remains, for now, a togglable switch to reenable support for them, it does sound like they're going to be disabled by default going forward.

@Tulip On a clean install of current Chrome Stable (version 131), Ublock Origin (a Manifest V2-exclusive extension) can still be installed from the Chrome Web Store and works out of the box without having to change any settings or toggle a switch to enable it. This is also the case in current Chrome Canary (version 133). Functionality to support fully disabling Manifest V2 extensions at all was only added just last week (but is itself disabled).
Based on Chrome's release schedule (https://chromiumdash.appspot.com/schedule) 131 (the current Stable version) will be the last Stable release during 2024. I consider it highly unlikely that the Manifest V2 extension deprecation status will change during the current Stable version.

We expect it will take at least a month to observe and stabilize the changes in pre-stable before expanding the rollout to stable channel Chrome, where it will also gradually roll out over time.

Will you resolve yes if Manifest V2 is disabled for 10% of stable users?

@SavioMak Thanks for asking. Let's say it has to go to 100%.

@tfae Clarified that it must stay at 100% for a week.
