vdevs. That is, a raidz vdev can be built across a bunch of mirrored vdevs, and
a mirror can be built across a few raidz vdevs.

You are incorrect.
The man page states:
Virtual devices cannot be nested, so a mirror or raidz vir-
tual device can only contain files or disks. Mirrors of mir-
rors (or other combinations) are not allowed.
A pool can have any number of virtual devices at the top of
the configuration (known as "root vdevs"). Data is dynami-
cally distributed across all top-level devices to balance
data among devices. As new virtual devices are added, ZFS
automatically places data on the newly available devices.
