I thought about this idea some more, and I'm not sure it's a good idea to use ALL the polygons. Municipality governments tend to have several competing "wijk" concepts, that usually are not official (ask me how I know). Their names might coincide with what citizens think of when they say Brugse Poort, but they might be defined differently. For example the Gent "wijk" boundaries are bound to be based on statistical sectors (as defined by statbel). But when those don't exactly match with your idea of a neighborhood, they still are respected for practical reasons. The "wijk" boundaries also cover the entire territory, even if there is no local concept of the area being a "wijk" in the heads of the citizens. E.g. I don't think anyone would say they are from "Stationsbuurt Noord". I would propose only adding polygons for those neighborhoods where you feel they are clearly defined (i.e. verifiable). This should be enough to stop a data user from applying a "Malem" label to an address that is clearly outside that neighborhood, without labelling all adresses with a semi-random neighborhood.
The fact that "wijken" do not exist as a Flemish or Belgian level administrative devision, means that it is hard to define how they should the admin_level structure for admin_boundaries in Belgium; even if the municipality would have officialized their existence at all.
