I agree - if you were thinking of later relaxing this constraint to
allow the server to supply tag ref information during tag following,
writing "MUST NOT" here is still fine. (We can later change this to "if
'include-tag-ref' is sent, the server MAY send refs which were not
requested, otherwise, the server MUST NOT".)

Both Jonathan Nieder and I also suggested client enforcement [1] - I see
that in patch 8, in receive_wanted_refs(), unrecognized wanted-ref lines
are silently ignored. Maybe at least a warning would be good.
