I think the support of duplicate keys is a very much needed feature and 
I personally would drop it only, if there are really good reasons (e.g. 
breaking fast queries, etc.) to drop it.

It would be possible to tag something like "amenity=supermarket; 
post_office;" but as stated in another discussion yesterday that would 
make searching for entries much more complicated.

Just to name a few very common cases where duplicate keys would be 
necessary I'd like to point out the very common case of hotels also 
having a publicly available restaurant. Of course one could draw a 
building and drop all needed amenities inside, but I think that wouldn't 
be routable unless you add the addr: properties to every node inside 
that building.

So personally I think duplicate keys would be the easiest and best way 
to tag such double-uses.
