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.
