Comment(by pramsey):

 Well... "I want to use geography, but I don't want geography semantics"
 seems like a hard mandate to fulfill in general. If you really don't want
 geography semantics, use geometry instead, right? Densification seems the
 obvious first route to fixing particular rectangle issues, in much the
 same way one would have to densify a correct great circle line to get
 geography semantics inside geometry. As a more general proposition, your
 post is the second in as many days with the same issue ("square" boxes not
 being treated as people expect, probably as the result of query rectangles
 being drawn on projected maps) so if there's a general utility function
 that makes sense we should provide it.
