My understanding was that 'zfs send -D' would use the pool's DDT in

It does not use the pool's DDT, but it does use the SHA-256 checksums
that have already been calculated for on-disk dedup, thus speeding the
generation of the send stream.
Ah, thanks for the clarification. Presumably the same is true if the
pool is using checksum=sha256, without dedup?
Yes, I think so.
Still a moot point for now :)
