This debate may run and run!!!
For myself, I will probably continue using seals on inlets to avoid blue smoke, coke formation and poor emissions. For the exhausts, I don't really see the function, although I would use them if specifically required by the manufacturer.
It could be argued that the small amount of oil which gets past seals aids lubrication, and that the exhaust stems need to be without seals to get any oil at all !!

All best wishes for 2021 to all Volvophiles😊😊!!
