I agree with this statement.
My only experience with this was on my dad's 78 Volvo 245 wagon.
One particular shop removed it to do some work to the cooling system.
When the failed to replace the belly pan, the PS rack boots split shortly thereafter.
Also while on the highway the car's steering would wander all over the place (lack of pan made the lower section act like a wind sock at high speeds (for a Volvo)).
Once the cover was replaced, everything went back to normal (for a Volvo)
+1 they reduce corrosion of components in the rust belt. They are a pain but you are driving through gritty salt water for most of the year, after all.
