This has taken so long I originally switched to Firefox a little less than ~4 years ago, switched back a couple years later and continued using v2, and have now switched to other Chromium based browsers that weren't even announced at the start of this journey.
It'll be interesting which Chromium downstreams end up maintaining manifest v2 vs which pitch built in blocking a la "but we have adblocking at home" style and how that actually pans out in where the power users go.
Based on current trends, it seems Brave will be the only browser that maintains Manifest v2 support in Chrome. They have a specific panel in settings that allows installation of specific extensions, including uBlock Origin.
Brave has been a bit gray about it. E.g. sure they have that panel and say they'll do things to support it but then when pressed on how they'll say they'll only keep doing that as long as the code paths remain in Chromium. I.e. they are more than willing to keep it enabled but not necessarily willing to commit to maintaining it if/when it is removed from upstream Chromium.
(I'm probably in a minority)
