The problem with this is that you'd have to know where the bounds are,
which seems to be the unknown here.

As far as defeating automatic bounding (which cannot be entirely turned
off--See clipka's comments in "Apparent bounding bug in sphere_sweep,"
April 2013), I just intersect the object with a bounding shape, which
sidesteps the issue entirely.  Potential problems with this approach are
performance issues with complex unions, and that it may not work with
cubic sphere_sweeps.
