This is a crazy situation. Unless something changes many millions of Chrome users are going to find that the extensions they depend on just stop working next January. As noted here many very popular extensions have not been updated in years. The transition from a long lived background process to stateless service workers is non trivial in many cases, or impossible in others due to bugs. The silver lining is that as an extension developer (eg me -> https://braintool.org https://braintool.org) if you have a V3 extension you might be in a position to pick up a lot of new users during the transition!
