That's really a statement about servers, not clients, so I'm not
convinced it's relevant here.
It's true that servers are not required to support optional attributes.
But obviously clients may be required to do so if, for example, they
want full control over file permissions.
The chmod-modifies-group-bits scheme only removes one of the more
visible consequences of this fact.
