I assume you're being downvoted because of the unnecessary political commentary.

However, I am curious as to the process for getting a kext signing cert, as that plays a part in the value of having the certs in the first place or not.

I didn't mention anything about serial numbers and the fun and games that goes on there when trying to get a Hackintosh working with iMessage/Facetime/iCloud services, which is a bit of a mixed bag. There could be security implications related to that, that haven't been worked out of the woodwork yet, but the kernel extensions feels like the biggest risk there.
