Isn't this what Helium is doing? I have been using it as daily driver for half a year, works a charm. Only would like better 1Password integration.

Helium is based on ungoogled-chromium. It enables manifest v2 by simply reverting some code changes made by google. So, if google decides to remove manifest v2 wholly, helium will also lost its ublock original support.

Removing all manifest v2 support is also a code change that can be reverted. Of course, the larger the change, the more work it's likely to require to maintain it in the future.
