It's kinda sad all these Supernovas got their own chance to have CoA and CoO officialised while a bunch of characters will never be due lack of 2.0 Cards.
I mean, Kid, Killer, Drake, Hawkins and Apoo were not declared as haki users when their first card was published, even if their was the post-timeskip version already. The updated version has it. Pretty surely the same will go for Bonney and Apoo when they'll get their shiny moment. But Bege missed the train as his was the first and only own card (until if he'll get enough spotlight to achieve a new card sooner or later, which I fear he won't).
This discrepancy between two cards of the same character bugs me. Just like Jack, if Ivankov and Kuma will get a new character arc, they'll prlloy get officialised as haki users (would be kinda odd if the four horsemen of revocalypse do have both basic haki and the actual Grand Leader Officer doesn't).
And I can't really believe Magellan, the actual director of the greatest prison of the WG hasn't them either when all CP9 agents but Spandam are proficient users. And what about some ever-standing characters which have already proven to have fought New World great names like Crocodile or even Moriah? Of course there could be justifications for it, as maybe Moriah is literally too lazy, but Crocodile fought Whitebeard in his youth and Mihawk/Doffy/Sakazuki at Marineford. He'd really be able to exchange blows with all of them and survive unharmed without a glimpse of CoO and CoA when even Diamante, Trebol and Pica have it? Is it narratively safe to have (former) Warlords without haki? (Buggy is out of topic for obvious reasons. And even there I can't really handle a pirate which actually lived under Roger's wing don't at least have a hint of dunno CoO. Maybe never developed, but–).
