I think that the species is at a point where trying to rebuild it from the 5 extant members is irresponsible. they're going to end up like Cheetahs, with problems from inbreeding. I think we have to accept that we've failed to save them and let them go.
trying to rebuild it from the 5 extant members
The species would have issues, but with effort from human beings, through programs such as introducing new genes (No idea how that would be done), or just curing issues from inbreeding, a population can be brought back.MVP does not take human intervention into account. Thus, it is useful for conservation managers and environmentalists; a population may be increased above the MVP using a captive breeding program, or by bringing other members of the species in from other reserves.
