This is insanely cynical. The optimistic version is that many teams were already home-rolling protocols like A2A for "swarm" logic. For example, aggregation of financial data across many different streams, where a single "executive" agent would interface with many "worker" high-context agents that know a single stream.

I had been working on some personal projects over the last few months that would've benefitted enormously from having this kind of standard A2A protocol available. My colleagues and I identified it months ago as a major need, but one that would require a lot of effort to get buy-in across the industry, and I'm happy to see that Google hopped in to do it.
