If such changes had been planned in the project all along and the money injection can help speeding this process up that's fine. But I can't see Google security people getting involved being a good thing otherwise. They come across as prioritising security problems over anything else (e.g. "if all you have is a hammer...") and I'd be surprised if this sort of extremism will be healthy for a project in the long run. Memory safety is just one of many aspects to juggle in a software project.
