Rear Alignment: Drivability vs Economy

I'm fixing the alignment on the rear of my car... I'm wondering the "if and why" of the OE Toe-in/out in my service manual...

The factory service manual (which doesn't always provide "perfect"/Ideal numbers).... has the rear wheels Toe'd In by 20' (1/3 degree), or a total Toe-In of 40' or 2/3 degree... I'm thinking about the "why"?

I assume there is a stability benefit to having your rear "Toe'd In"?

Would I benefit economically if I were to manually set it to a more neutral "Zero"? My rear end is pretty ehF'd as it is (until I do the alignment), but with a neutral rear end, would I run into drivability issues?

I should add this is a FWD car with a solid rear axle beam
