I disagree, in the heavy duty segment, Cummins/Fleetguard in the filter install instructions regardless of the size of the filter shows prefilling the clean side threaded hole and lubing the gasket prior to installation.
There has been recent demonstration showing prefilling does less wear on startup compared to a dry filter by some tribologist at youtube we pretty much all know here.

Here's a Donaldson sample showing the same instructions... massive filter btw.
