Now that MacPorts has the sqlite registry which does remember turned-off variants, we prefer positively-named variants, specified as default variants where applicable, that the user can turn off if desired (e.g. "-x11": "turn off the x11 variant").

The flat registry actually does store negated variants as well in
MacPorts 1.9.0+.
