Seven attitudes have certtinly changed since the 60s! If so concerned about wear what lengths are gone to to avoid short and cold runs, starting just to move etc, all conducive to condensation the main Seven enemy? I suspect the main source of metal is the timing gears, esp with increased output, but persons do not desist on the basis of more detritus.
The lasrt "modern" I put rings only in I retained the filter, put back settled old oil, then replaced all after 100 miles.
For the car which has stood removing the sump before start up would get rid of all metal dertritus.
For those without filters drained oil can be poured through a modern filter.
From what I have read a thermostst would likley reduce wear more than all the draining rituals.
