I installed an alternator kill switch on my 1998 Civic DX for the exact purposes you describe. I also use it for a crude, mild regen braking tactic: slow-down using DFCO with the alt turned to "on" position. No fuel burned, no friction brakes used, electricity generated (though not a lot, and prolly not well absorbed in my deep cycle batt).
