@freemo I think you misunderstand form versus function and are inadvertently arguing my case for me. I argue that the function of a walled garden is 'demarcate a space using a structure delimiting an enclosed inside and relative unenclosed outside'. The figurative windows and walls are indeed formal rather than functional, and holding the opinion that these formal addition make the garden more or less transparent according to what appears to be a 'publicly-accessible documentation' centric model of transpsparency do not change the essential walled garden.
