That's unfortunately not the case. Device removal has been implemented in
Delphix but not yet upstreamed to OpenZFS / illumos. We hope to upstream
it in the next 6 months.

With device removal, there is no pre-set "grace period"; you can remove a
device even long after it has been added (though of course it might have
more data stored on it which will take longer to move).
