I've worked with them, I've written code to upload them, and I've seen firsthand how their absence bricks a system. With the risk of sounding arrogant, that gives me the credit to avoid your uninformed lecturing. You have the option in coreboot to not include them. Period. What I gather from your description is that you want is the CPU that works best without microcode updates. Ask around, or test yourself. I don't think many people have tested without microcode updates.
