Whatever reason Kubo has for giving Kenpachi Bankai, and for the way he did it, still has to be revealed and explained. Sure, it did happen seemingly rushed and against his own previously given rules for achieving Bankai, but I think we should hold off on Kenpachi's case until Kubo explains it properly.

As for Ichigo, both Hollow Zangetsu and Quincy Zangetsu seem to be in harmony with him, so I think Ichigo could still have a Bankai. After all, Zangetsu have existed for a long time already despite only recently being forged with an actual Asauchi. I guess it comes down to whether or not Zangetsu himself wants to let Ichigo use/keep using his Bankai state without having to re-achieve it.
