Gin, Mayuri, Rose, Tosen and Retsu are all dead, except Mayuri but we now he didn't achieve Bankai like the others, he created and modify his zanpakuto and even if the others were alive the concept was introduce in this arc. Or maybe is only given to does who train in the Royal Realm, Ichibei could have taken Yamamoto to the Royal Realm and teach him the full name of his zanpakuto.

I assume this because fake Yhwach said that Yamamoto's Bankai change from 1,000 years ago will saying what you said that Bankai's don't change randomly. Yamamoto had the same problem as Renji.

Why is it that the Zero Squad and Yamamoto's zanpakutos are not in a form of a normal sword before release? Yamamoto's zanpakutos was a wooden stick before release. But this contradicts Renji, Rukia and Ichigo's new zanpakutos looks, so it doesn't count. I'm not saying that you are wrong either, i'm just speculating what would happen if this was true?
