I think that it is a poor assumption to make that there exists a one to
one mapping between objects (nodes, ways, relations) tagged with
amenity=university, and actual organisations.
For example, you would not count the roads in a town by looking at all
ways tagged with highway=(primary|secondary) in that town, as more than
one way can make up just one named road.

I have been doing some things around the University of Southampton, I
have just made an attempt to bring the wiki page a bit more up to date
. It should now cover some of the basics.
As for the tagging, for the University of Southampton, none of the
software that I have written (e.g. ) relies on amenity=university. I
am pretty much only relying on the URI's (uri tag) to link out of
OpenStreetMap. This allows for going in to OpenStreetMap and identifying
bits of information.
In summary, I am not sure what amenity=university means, or should mean,
however, it obviously plays a part in rendering OSM. I am unsure about
relations, I think it remains to be seen if they are fit for purpose in
