Void boxes are a STRICT no-no anymore!

Huh?  You must have dreamed this!  In expansive clay areas, we continue to routinely specify void boxes under all grade beams, pier caps, and tilt-wall panels.  As far as I know, so does everyone else in Texas (except for you, apparently).

Based on previous experience with poor construction practices on many projects, we no longer specify void boxes under structural slabs.  However, many other engineers don't appear to have any problem doing so.
