Analyze the possibility to use Records on sum types when the interface is not updatable

[jodinathan]

VSCode extension API has this function:

export function createWebviewPanel(viewType: string, title: string, showOptions: ViewColumn | {
			/**
			 * The view column in which the {@link WebviewPanel} should be shown.
			 */
			readonly viewColumn: ViewColumn;
			/**
			 * An optional flag that when `true` will stop the panel from taking focus.
			 */
			readonly preserveFocus?: boolean;
		}, options?: WebviewPanelOptions & WebviewOptions): WebviewPanel;

Records aren't updatable so we can't use it freely with sum types, however, when the sum type is being used as an input like WebviewPanelOptions & WebviewOptions above, we may be able to generate a Record to be used instead of Object
