Comment (by pramsey):

 If the problem is "how can QGIS get a bounds for the data set" that's a
 little fiddly. In general the answer to "how do I get a 'normal' box" is
 "just use geometry". But for estimated extent that's not really on the
 table, as the information we want is already in geocentrics. One could
 take all the corners of the geocentric box, convert them back to degrees
 and then take the geometry extent of the collection...
