Don't call out a specific date; it's very subject to change.

The flow is a little odd right now; could we switch to:
format_requestis the entry point and what the model calls internallyformat_requestchecks if_format_requestis overridden; if it is it emits a warning and calls it, otherwise it invokes_format_request_impl(which is the default implementation) which calls_format_request

I think we're also okay breaking users of _ as well given that it's marked as private.
That's what we went with for #2370

…_streaming public
Description
Users building custom Bedrock integrations need to format requests and convert non-streaming responses outside of the standard stream() flow. For example, to inspect or modify the request before sending, or to integrate with custom invocation pipelines. Currently these capabilities are only available through private methods (_format_request, _convert_non_streaming_to_streaming), making them fragile to depend on and inconsistent with other providers (Anthropic, Mistral, Ollama, Writer) that already expose public format_request.
Public API Changes
BedrockModel now exposes two public methods that delegate to the existing private implementations:
Before: rely on private API (fragile, undocumented)
model = BedrockModel(model_id="us.anthropic.claude-sonnet-4-20250514-v1:0")
request = model._format_request(messages, tool_specs)
events = model._convert_non_streaming_to_streaming(response)
After: stable public API
model = BedrockModel(model_id="us.anthropic.claude-sonnet-4-20250514-v1:0")
request = model.format_request(messages, tool_specs)
events = model.convert_non_streaming_to_streaming(response)
The private methods now emit a DeprecationWarning when called directly, with removal planned for September 2026. Internal call sites continue dispatching through the private methods (with warnings suppressed) so subclass overrides are honored without behavioral changes.
