Well, it's complicated (I'm using that an aweful lot when it comes to discussing CFYOW), but the name thing is afaik more of a conscious decision on either side to prevent full power form being used against either's (or both's) wishes. Kazeshini is explicitly stated to be more similar to Zangetsu and Nozarashi in this regard. It was not (necessarily) ill will or a conscious decision that prevented Hisagi and Kazeshini from cooperating properly, it was just a severe lack of connection and understanding between them.

Hisagi gravely misinterpreted what Kazeshini was really about (and Kazeshini resented him for that) and therefore the two were horribly out of sync preventing them from truly realizing their potential.

I agree that it was not necessary to be retconned into a kido type rather than a melee type, but I suppose it was for the sake of plot.

Interesting that you brought up Sogyo no Kotowari, as it was explicitly stated to be a dual type because of Mimihagi's influence. But it's still primarily two swords that are connected. Kazeshini is even stated to be the chain itself (more evident in bankai), and the scythes are just there to improve upon its offense.

As for the bankai, it stated to be more useful when Hisagi has people backing him up. So he can wear down an opponent (on Kenpachi's level even), and then his allies can move in to finish it.
