If you take off the sump of many modern engines they have both scrapers and trays, or a combined complicated looking integrated thing that hugs the crank and appears to fill most of the space in there.
and those engines are designed to get you to the shops
or take the familiy on a road trip.
few family cars spend much time at 6000 rpm most live a life between 1000 and 4500.
that engine is sitting in front of a transmission with potentially 2 overdrive gears. 70 MPH 1500 rpm
if it wasn't worth it they wouldn't be investing in $15 of extra pressed steel and a tiny bit more mass for every engine produced, if it didn't make more power or get better economy.
both of which are a concern for the retailer and the purchaser these days
if you have been hit on the head by a bottle of oil....you know it has mass.
and if you have belly flopped into a pool you know how hard a liquid can be when you slap into it.
flown in a plane through clouds and thermals.... etc etc
scraper and tray makes sense to me
