I don't see any technical reason why your encryption/decryption route couldn't sustain one branch. You're doing it in hardware, there's not going to be a performance decrease from it, though there would be a slight increase in chip complexity. Apple have taken the decision here that abandoning the ability to recover data from failed machines is worth the guaranteed security floor of it not being possible to disable strong encryption, and honestly I find it hard to disagree.
