Question Does trailer-hitch remove the “impact absorbent” safety feature?

For most cars, there are bumper and impact-absorbent behind the bumper cover.
My understanding is the “impact absorbent”'s main purpose is to absorb the forces during impact as safety feature so that the forces will not all transferred to the car frame and eventually to the car passengers.

Now with the trail hitch that is mounted to the car frame and exposed outside the bumper cover,
Does it mean; at rear-impact collision; the impact-absorbent is bypass causing the impact forces at transferred directly to the car frame then to the passenger?

Can anyone shed some light? Thanks.

If the forces are anywhere near strong enough to cause injury the trailer hitch will probably break. I thought impact absorbing bumpers were to keep the car from getting damaged in low speed collisions.

Old folks remember the old 5 mph bumpers, but those don't exist anymore

Fronts are now 2.5 mph and rears are nothing.

These requirements NEVER applied to trucks, pickups, SUVs, etc.

These requirements were directed at reducing insurance costs of minor bumps. They were never considered safety features.
