No, but for geli hifn(4) crypto(4)/(9), geli(8) might work
if aes-cbc is indeed the mode geli uses. See the source I guess.

Yes. There are trays and cable dongles and things that do aes/des.
And some drives are coming out with it in firmware. Does anyone
like the cost, closed-source, and trust model of such hardware?

I'm partly up against this because some failing drives are negotiating
lower speeds for themselves. Never thought of is as a test tool though.

ZFS handles that and informs user about silent corruption. Precisely
because of the chained checksums. It's quite addicting.

Your little to no overhead for ffs sounds right as always.
