Are you certain? The last I heard about it from Vivaldi[0], they were only going to keep the MV2 code around so long as it's in the upstream codebase:
> We will keep Manifest v2 for as long as it’s still available in Chromium. We expect to drop support in June 2025, but we may maintain it longer or be forced to drop support for it sooner, depending on the precise nature of the changes to the code.
Note that June 2025 is the same date Google plans to drop support completely[1].
