I suppose that I agree to a limited extent, but virtually all
crankshaft/connecting rod failures are caused by a flaw/fault in
design/manufacture or installation. Once the crank or connecting rod is
installed, nothing is done to it and it is unseen until overhaul time. A
failure of either of these components is not going to put much, if any,
metal into the oil until the bitter end either..

Well there is no maitenance on connecting rods and crankshafts.

But do you agree that components that require maintenance (propeller,
cylinders, engine mounts, ...) can cause/accelerate crankshaft
failures?
