Yeah, once Google has ripped all the MV2 code out of chromium it'll be very interesting to see how long the chromium reskins are able to maintain their private forks.
I also expect Google to be a bad actor and do everything in its power to pointlessly refactor the chromium codebase specifically to make keeping MV2 alive as painful as possible.
Ai will help here, I maintain several forks for software I use to add a feature or two
