I've done that (exporting V4: /)

but then when I mount a sub zfs filesystem (e.g. /pool/backup/sites/m)
then it appears empty on the client.

If I export /pool/backup/sites/m , then I see the content of the directory.

Most of the sub-directory in /pool are actually zfs file system mounted.

It is something I expected with NFSv3 .. but not with nfs v4.
