What the current evidence supports

Human editorial judgment · 2026-07-21

Proceed with caution

Why
Spec hit v1.0 with strong neutral (Linux Foundation) governance, three transport bindings, and real cloud GA — but independent analyses (Glukhov, CSA MAESTRO, arXiv surveys) consistently flag identity/trust, discovery exposure, cross-protocol delegation, and marketplace prerequisites as unsolved. 'Supported by' is not production use; adopt for narrow cross-ownership agent collaboration, not as default infra.
Next
Pilot A2A only on a bounded, trusted-boundary inter-agent flow with signed Agent Cards mandatory, OAuth2/mTLS auth, and explicit audit logging; map against existing AP2/ACP protocol layers before any production wiring (Rules 2, 4, 28, 29).
