I'm the first to admit I know next to nothing about this, but given the findings by james194zt with regard to
AES/CBC/PKCS5 encryption with SHA2 256Kb hashes, is cracking KFX even possible at this time? Or is it a waiting game until Amazon releases (if they release) a KFX-capable Kindle for PC/Mac app or kfxgen utility?
(I'm not being snarky or sarcastic. I honestly want to understand the process as much as my limited brain can grasp.)
Also, I'm really worried mattmc is right when he says:

I mean, I could be wrong, for sure. If Amazon starts passing out the kfxgen utility so creators can properly proof their books, then I was wrong.
