Comment(by srstclair):

 GeoTools now has the ability to use ST_Simplify when rendering tiles from
 PostGIS. The polygon nullification behavior wasn't expected and caused a
 bit of a debugging headache:

 http://jira.codehaus.org/browse/GEOT-4737

 This behavior basically prevents ST_Simplify's use in map tiling
 applications. As strk mentioned above, using ST_SimplifyPreserveTopology
 isn't an option since it's usually much slower than just returning the
 original geometries. So, +1 for adding policy control argument(s) to
 prevent nullification of polygons.
