V6 3.7 Duratec Water Pump Drive Chain Design Flaw?

Anyone have knowledge concerning a design flaw in Ford 3.7 6 Cyl Duratec Engines in 2011-2014 mustangs (at least)? There was a class action suit against Ford (Bobby Roe and Donald M. Christenson, et al., v. Ford Motor) for a poor design since the engine’s water pump is powered by the drive chain and if the Water pump fails antifreeze will mix with engine oil destroying the engine without much warning after overheating? A recent Scotty Kilmer Mechanic YouTube video stated this issue and that water pump replacement, due to integration with the drive chain, can cost upwards of $1,500 if your engine is not destroyed after a water pump failure? What prevention measures can be taken to prevent a water pump failure? $1,500 for a water pump replacement OUCH!!! Thank you to all who respond.
