Just about any 'abuse' of an engine that will knock out the main bearings will ruin the rod bearings long before any main bearing symptoms would ever show up.
Not true in my experience or in the experience of the engine rebuilders with whom I work regularly. We and they see low RPM damage of main bearings when the rods are still in perfect condition.
Packard V8s are especially susceptible to main bearing wear. It's usual to see a Packard V8 with the mains turned .010" under and rods and bore still standard. If the engine has had hard use or been apart once, the cranks will often have to be .020" under and rods only .010" under.
