Yeah and the shock absorbers that were part of the bumpers on the old skool big chrome bumpers when the USA first brought in the 5 mph bumper requirements (1973-ish?) have long since been replaced with "crash cans" that are built into the structure of the bumper - the piece underneath that everyone calls the "crash bar". The piece that extends back to where the crash bar attaches to the unibody is intentionally deformable ... once!
There was a time when the bumper standards originally came out that the car was supposed to survive the 5 mph hit without damage. Those days are long gone. The worst offenders are some compact CUVs in which the hatch extends down into what is cosmetically the bumper, and the distance between the hatch and whatever you back into, is 0. Some of them have designed a replaceable panel into the bottom of the hatch ... but it's still a painted part, which means it has to be painted to match if it ever has to be replaced.
