This was a deliberate decision. The idea was to restrict it enough to
make this a one-dimensional "label", but not more. This way apps
processing this setting have enough information at hand to compare and
order this values, even if there's no vocabulary enforced what the
user puts there. See the man page of "hostnamectl" for details about
the syntax.
