Because the word hasn't gotten around to most electrical engineers that it
doesn't work like they think it should.  So it continues to be done, and
many engineers wouldn't think there is anything wrong with it.

On first glance it seems like a reasonable thing to do, akin to putting a
shield around a wire, turning it into coax.  Reality is another matter.
