The catch is that, as of current master, you would have to configure
trusted-keys/managed-keys for each zone you would like to mirror.  In
other words, the chain of trust from the root is currently not
established automatically when a mirror zone is validated.  This might
change in the future, but since the root zone is the primary use case
and a default trust anchor for the root zone is installed implicitly, I
would not hold my breath for it.
