A conspiracy theorist might suggest that, if MAJ was a 'suitable' , then, under the QF rules, the PIC may feel more obligation to land there, (CAO 20.6 notwithstanding, as discussed in this thread)... I guess QF, like all other airlines, wants the a/c at the dest rather than another port.
The only reason that airports like MAJ (and PHTO and PLCH) are even up for discussion is to be able to dispatch a two-holer from (say) SYD to HNL or west coast USA legally on the 180 ETOPS rule (A330). No-one wants or even envisages going there. IMHO, thats why they are categorised this way..
