Oil pan gasket vs rtv

I want to have a discussion about oil pan gaskets. Not brands or materials or leaking issues. But a discussion of WHY? Do we all just put those paper/composite gaskets on because we always have and then all just agree that they HAVE to be there? I recently worked on some other vehicles that don’t even come from the OEM with a gasket for the oil pan, just black RTV gasket maker. If it’s good enough for them, why couldn’t it be ok for us? I’m not saying I’m going to go this route with one of my engines, I just want to know what cork or paper can do to seal better than a form fitting/imperfection filling liquid that hardens in place. Anyone done it without gaskets? If so what were your results?
