Maybe the switch will allow some more creative control over the process.
Side note: it seems to idle fine at 400-500 RPM -- could this be a fuel saver? I tried the A/C and maxed-out the electrical load and it was fine -- no stalls.

Short Answer, Yes.
Low rpm will still deliver adequate oil distribution to all your vitals in the engine, and in a manual trans.
Caveat to auto owners, most of the autos in passenger cars have a stall speed near ~ 1200 rpm.
This means below 75% or ~ 800 rpm there is not enough fluid pressure in the torque for operation. AND.
below 50% or ~ 600 rpm there won't be enough fluid pressure to lubricate the rotating assembly in the case.
I can't remember which tranny you've got, and they are not all identical. These are just rough numbers.
That Said,
Many newer cars use fuzzy logic in the controls for the engine and follow your particular driving habits to keep the rpm as low as possible at idle.
SOOO
For greater savings, lower idle is better, no idle (EO) is better still.
Since my car is three colors of blue with one black fender, I get many
DIRTY looks when I restart at lights. toobad soosad yourdad,
they also hate me when I put in $11.5 at the pump and tell 'em I've been driving for three Weeks.
