Oil filter is horizontal on my engine so have rely on residual oil in bearings etc.
The only vehicle I can prime the filter on is my 1971 Lotus Elan - the modern cars have paper elements with holes at the bottom of 'bowl'
Whilst I do drain thoroughly (with vacuum system) I always fill up straightaway so I don't reckon the wear is significant and must be what the manufacturer expects.
When starting an engine after rebuild or standing for months I'd reckon to remove spark plugs to allow oil circulation without combustion loads. But not a lot of chance for that on a diesel
