Yes, well... they are used in automatic bounding and in "manual" bounding.

From the 2.0 docs:

...
POV-Ray attempts so speed up the process by building a set of
invisible boxes, called bounding slabs, which cluster the objects together.
...


Version 2.0 did not have further bounding optimisations like vista-buffers,
light-buffers or the hierarchy of nested bounding slabs. However, for
certain
scenes, speed improvements were remarkable.
(that's why I remembered in the first place)
