Lazy HTTP connections seem to make error handling difficult.

Question

When using streamablehttp_client, since HTTP connections are initialized with anyio.create_task_group, if the server is unreachable, an error will occur unexpectedly at some point later. Is this the intended behavior? If the connection is impossible, I want to wait and handle the error. However, the current behavior executes the code after the initialization and then throws an error at some point. If the error had occurred earlier, the code below it wouldn't have needed to execute. I consider this excessive optimization. Is there a reason for this design?

            await session.initialize()
            return await load_mcp_tools(session)
    except Exception as e:
        return []

            await asyncio.sleep(100) # << A httpx.ConnectTimeout exception occurred while performing the following operation!!
