From the docs:

ceph.rbd.clone_copy Whether to use RBD lightweight clones rather than full dataset copies.

That seems like a pretty trivial bug, can you file an issue at https://github.com/lxc/lxd/issues?

After I posted this I realized it was able to be set on pool creation however, with the feature successfully set Ceph is still creating parent/child relationship images.

Not sure if the two are related.
