No it doesn't. Getting a whitelisted code signing key just requires you to agree that you won't distribute malware. You pay nothing for it and Intel don't see the code you sign. Please don't make things up because they "sound right".
Only Intel know what chips they've manufactured and what microcode patch levels are currently considered secure, so that wouldn't make much conceptual sense. But the new DCAP feature lets you run some of the RA infrastructure yourself, yes.
