Workflow Space nodes show too many optional inputs and outputs

While testing Gradio Workflows, some Spaces show too many inputs/outputs by default. Example: Stable Diffusion 3.5 Large, one of the featured Spaces under Image, appears with many inputs/outputs. It is unclear why some inputs are gray, possibly because they are not required. <img width="1504" height="806" alt="Image" src="https://github.com/user-attachments/assets/428b4d15-7c0b-421f-b9d9-5278a41637e4" /> Expected behavior: non-required inputs should not be shown by default, or the UI should make their optional status clearer.
