Google's A2A protocol sees hype but little production use yet

A Reddit survey of developer discussions and vendor announcements around Google's agent-to-agent (A2A) protocol finds most teams still at the "evaluated it" or "plan to use it" stage rather than running it at scale. Momentum on the standards side is real — partner counts keep climbing and A2A is increasingly framed as a complement to MCP, not a competitor. The author caveats that visible signals are public commentary, not production telemetry, so actual adoption depth is hard to verify; A2A is becoming the default reference point in these conversations without proving most production systems have switched from custom protocols.
