1. An apparatus for deployment within a passage of a wellbore flow conductor disposed within a wellbore, the wellbore passage being defined by a passage-defining surface of the wellbore flow conductor, comprising:
an actuator;
an engager including:
a sealed interface effector; and
a sealed interface effector supporter including:
a first supporting member including a first free end and a second free end, such that a first gap extends from the first free end to the second free end; and
a second supporting member including a first free end and a second free end, such that a second gap extends from the first free end to the second free end;
wherein:
the first supporting member is disposed between the sealed interface effector and the second supporting member;
wherein:
 the apparatus is configurable in an expanded configuration for co-operating with the wellbore flow conductor for establishing a sealed interface within the wellbore, wherein the sealed interface is established by sealing engagement between the sealed interface effector and the passage-defining surface, wherein, in the expanded configuration, at least the actuator and the sealed interface effector supporter are co-operating to establish a supporting-effective configuration for opposing defeating of the sealed interface, wherein, in the supporting-effective configuration:
 the first gap defines a first expanded configuration gap;
 the second gap defines a second expanded configuration gap;
 the first expanded configuration gap is offset relative to the second expanded configuration gap, such that an occluding portion of the second supporting member is occluding the first expanded configuration gap;
 the second supporting member includes an end-adjacent portion, wherein, relative to the occluding portion, the end-adjacent portion is disposed closer to a one of the first free end, respective to the second supporting member, and the second free end, respective to the second supporting member; and
 the axial length of the occluding portion, as measured along a longitudinal axis of the apparatus, is greater than the axial length of the end-adjacent portion, as measured along a longitudinal axis of the apparatus.
