Not in that configuration it's not common. Never installed on a factory application. All the oem automotive delco 10si or 12si are 3 wire only. They won't work without the regulator plugged in. Some like the summit you have will work either way but only because it was specially built to do so. Please understand that I'm not trying to argue with you. I've been working on these types alternators in countless variations a long time and I'm just trying to share a little knowledge.
