Optional fields are not guaranteed across providers

Required fields are guaranteed across every provider that supports this task. Optional fields may be honored by some providers and silently ignored by others. AnySolver does not document per-provider parameter support, so before relying on an optional field, check that provider's own docs for the task you are using.
