P1 gets my benefit of the doubt, cause he already showed basic CoO and because Ulti also has CoA.
Drake is just Drake. He should have it.
But I'm honestly not so sure on BM and Sasaki having it. Keep in mind that Ulti and WsW only showed it in conjunction with their "signature" moves. Even though they have it, they weren't really portrayed as very haki affine either.
So when BM and Sasaki get a whole fight, while Sasaki does not even use it within his strongest attack "Magnumceratops", it doesn't do too well for them.
You could even argue that BM uses her iron knuckles as a substitute for the lack of CoA
But I like it. This way basic haki types aren't just standardized stats and more story relevant guys like Burgess, Collosseum Chinjao, Smoker and Vergo aren't just some guys out of like 20+ Veteran lvl guys.
