What do you think about A2UI?

A2UI is a v0.8 Apache 2.0 protocol by Google (with CopilotKit contributions) that lets AI agents safely send rich UIs across trust boundaries. Agents generate charts, forms, cards, and interactive elements that render natively — without executing arbitrary code. Currently in public preview.
