Yea it does seem a bit over the top. However, I'm speculating here, on most vehicles the condenser sits right behind the front bumper and could easily be damaged in a frontal accident. That same accident could also provide an igniting spark in the same place at the same time. The refrigerant filled parts on my coach are further back and inside a steel box. In my opinion that reduces the likelihood of a problem but doesn't eliminate it. It comes down to a careful assessment of the likelihood and severity of a problem and one's personal risk tolerance.
