Because CIFS/SMB has no chmod operation :)

aclinherit=passthrough-x is a better choice.

Also, aclinherit doesn't override aclmode.  aclinherit applies on create
and aclmode used to apply on chmod.

Right.  That only happens from NFSv3 clients [that don't instead edit
the POSIX Draft ACL translated from the ZFS ACL], from non-Windows NFSv4
clients [that don't instead edit the ACL], and from local applications
[that don't instead edit the ZFS ACL].
