Hey! I'm an the Tambo team so I'll chip in. There isn't really any reason we couldn't support A2UI. It's a great way to allow models to describe generative UIs. We could add an A2UI renderer.
The way we elevator-pitch Tambo is "an agent that understands your UI" (which, admittedly, is not very descriptive on the implementation details). We've spent the time on allowing components (be that pre-existing or purpose-built) to be registered as tools that can be controlled and rendered either in-chat, or out within your larger application. The chat box shouldn't be the boundary.
Personally, my take on standards like A2UI is that they could prove useful but the models have to easily understand them or else you have to take up additional context explaining the protocol. Models already understand tool-calling so we're making use of that for now.
