Did I misunderstand?

A standard engine isn't going to be hurt from decel with momentary loss of oil pressure. What I mean by decel is, the engine went from having fuel and cylinders firing to running out of fuel and engine taking a few seconds to come to a stop. A thin layer of oil is around the main/rod bearings to absorb the punishment of the piston going into its compression stroke only to be exploded the opposite direction with combustion. This is violent on the bottom end as all the preload for the rod bearings and that particular connecting rod go from the bottom side of bearing(s) to, when combustion happens, to the top 1/2 of the connecting rod bearing(s) ( all in a split second). Without combustion, freewheel, all you have is the compression stroke causing stress which is absolutely nothing in comparisone to the grenade in the hole slamming the piston down that is called combustion. The biggest chance for airated oil to cause damage is when you regain fuel and the motor kicks back in again, but even then you would have had to fly in such a way that when you ran out of fuel and the engine is on decel to a stop, that you had enough neg g's or were inverted enough that oil never came back into the sump in the 1st place before you fired back up. Kinda like firing up your car after an oil change. Either way, I think if this was to be modeled it would be such a rare occurance that it wouldn't even be worth doing. Basically putting this in the bug tracker isn't correct IMO.

I agree with Bliss but...
Lets read the 3rd point again...
Seems it will damage the pitch which will return to fine and then overspeeding of the engine that will cause the damage.

Maybe I should put it up then or it will never get done?
