Most of the "oil" finishes you find today aren't true oil but oil/varnish mixes and don't need wax.
Sorry, but that is not correct. Oil finishes, almost universally, have a large component of wax in them. It makes them level out better and lubricates the application process.
Finishing oil is just oil, usually, and most contain driers.
eta: Waxes as a protection for all oil finished stocks is an outstanding idea with zero downside assuming no silicone is added.
