There are several reasons why I do not like tagging smoking rules on boundary relations. (1) It is difficult to map smoking restrictions in restaurants/bars/cafes to OSM tags. By default, smoking in all German states is prohibited but there are exceptions. Let's have a look at the exceptions in the State of Baden-Württemberg (south-west Germany): 1. Smoking is banned in all restaurants, pubs, cafes, discothèques. 2. Smoking is allowed at pubs if they are smaller than 75 m², do not serve hot meals and must not be entered by people below the age of 18 years. 3. Smoking is allowed at separated rooms at discothèques if these separated smoking rooms do not have a dance floor and the whole discothèques must not be entered by people below the age of 18 years. How would you now tag the boundary relation of Baden-Württemberg? Please note that a small pub (60 m²) does not have to allow smoking, i.e. you cannot tag defaults which are valid for all pubs. It is better not tag any default values in such states and to wait until a mapper visits the restaurant/pub and add the tags. (2) Such bans on smoking often extend on other locations, e.g. stations [1], public transport vehicles, public buildings, … How many tags do you want to add to boundary relations. (3) Boundary relations easily and often break, i.e. smoking rule data at OSM can often not be used if the boundary of a city/state/country is broken. (4) OSM data should be easily to use. Why should we force our data users to use boundaries if they just want to create a OpenCigaretteMap? (5) OSM data should be easy to contribute. Please keep the on-the-ground-rule in mind.
