If you're referring to section 9.1.3.D.8.b (Body/Structure) and the associated note:
NOTE: Integrated bumper assemblies are defined as those
designs where an external non-metallic bumper cover
completely encloses the primary energy-absorbing bumper
and where this cover could be installed in its normal position
with the underlying bumper removed. On cars with integrated
bumpers, the front spoiler or airdam may be attached to the
bumper cover.
That note is doing nothing more than defining an "integrated bumper assembly" as it directly relates to attachment of a front spoiler/air dam. This has nothing to do with removal of the external bumper cover or the underlying metal bumper structure. It's just a definition.
