Works fine, but...

I personally do this, if the point of interest is just the building. If 
it is a campus, however:

I converted a few of these to areas describing the campus, and deleted 
the GNIS nodes. The buildings on the campus only have building=yes.

An example: http://osm.org/go/TdV4TCuTS-- and a few more to the north of 
this one.

I did a complete copy/paste of all the tags that were on the GNIS node, 
to the school campus area, before deleting the node. If there ever is a 
new round of imports, I wouldn't think it's too hard to also check areas 
for already existing features.
