Couldnt you argue that a properly just built motor probably has an equivalent film of assembly lube?
My motor is from Tim @ MPR in south florida
On contact surfaces sure, but not oil galleys. In OP's case, it's more about flushing new oil in, not necessarily building to proper oil pressure prior to cranking. As soon as the engine starts to crank above starter speeds, the oil pressure will rise. Load is low enough to where no discernible wear is occurring.
And at the end of the day, there isn't a test on Earth worth conducting that will be able to pinpoint the difference in wear between startup methods. What you recommended is the best option. What I recommended is quick and economical, but I'd never suggest it for an initial priming on a dry engine.
As long as OP doesn't jackrabbit start the engine that has been sitting with old oil, it's gonna run just fine
