I'm not sure but a lot of people hypothesize that they will have to keep this feature for enterprise customers (not for UBO but other custom enterprise extensions that use manifest v2)

they can easily just blacklist ubo if they really wanted to remove it. And they can make it plausibly deniable - by blacklisting the extension id of anything that is in the chrome extension store that originally had manifestV2 (which will have some collateral damage, but obviously google doesn't care).

But that would also harm companies that actually intend to switch to a v3 based replacement but need a bit of time to complete the development.
