> Just one? How about if app would prefer either landscape or inverse-landscape?

It's a bitmask so one can specify any combination, here's the enum:

typedef enum MirOrientationMode
{
    mir_orientation_mode_portrait = 1 << 0,
    mir_orientation_mode_landscape = 1 << 1,
    mir_orientation_mode_portrait_inverted = 1 << 2,
    mir_orientation_mode_landscape_inverted = 1 << 3,
    mir_orientation_mode_portrait_any = mir_orientation_mode_portrait |
                                        mir_orientation_mode_portrait_inverted,
    mir_orientation_mode_landscape_any = mir_orientation_mode_landscape |
                                         mir_orientation_mode_landscape_inverted,
    mir_orientation_mode_any = mir_orientation_mode_portrait_any |
                               mir_orientation_mode_landscape_any
} MirOrientationMode;
