The Vercel AI SDK’s direct `anthropic` provider excellently supports [tool input streaming](https://ai-sdk.dev/providers/ai-sdk-providers/anthropic#structured-outputs-and-tool-input-streaming).

Additionally, AWS Bedrock [officially supports](https://docs.aws.amazon.com/bedrock/latest/userguide/model-parameters-anthropic-claude-messages-tool-use.html) this same streaming capability for its Anthropic Claude models.

Unfortunately, the current `@ai-sdk/bedrock` provider does not seem to support this feature, creating a parity gap with the direct Anthropic provider.

Could support for tool input streaming be added to the Bedrock provider to match the functionality available in the `anthropic` provider?
