A place for oil to deposit after leaving the crankcase to keep it out of
the air, I would imagine. Done right it might even get drawn back into
the intake and burned at various engine conditions (hence the PCV valve).

Yes, that's what it's for - but isn't it fed by the fuel tank vent line?
Which needs to go somewhere "safe"?

I think you need a place for crankcase pressure (from heated air, if
nothing else, and of course blow-by) to go.
