Section 18.50.3 says:

If there are
sessions (both idle and non-idle), opens, locks, delegations, 
layouts, and/or wants (Section 18.49) associated with the unexpired 
lease of the client ID, the server MUST return NFS4ERR_CLIENTID_BUSY.

It should say:

If there are 
sessions (both idle and non-idle), opens, locks, delegations, 
and/or wants (Section 18.49) associated with the unexpired 
lease of the client ID, the server MUST return NFS4ERR_CLIENTID_BUSY.

Notes:

Should not include layouts.
A forgetful client may not return LAYOUTS. In this case, a server will always return NFS4ERR_CLIENTID_BUSY on DESTROY_CLIENTID and end up persisting the client’s lease until it expires although the client is explicitly asking us not to.
