I don't like this proposal. IMHO we do indeed need a way to map fuzzy
stuff, but it shouldn't be done by drawing an "unfuzzy" way (or node or
polygon) and then declare by tags that it is not to be taken literally,
i.e. that there is no such way in reality but just a fuzzy border somewhere
near that way. Rather we should tackle this on the datatype (or relation)
level and invent some fuzzy objects that are already fuzzy in the way they
are mapped (e.g. a group of nodes (or other objects) that define an area by
saying "I'm inside" and maybe "I'm outside", so that dataconsumers could
calculate an approximation for this area for their needs).
