In this case, there isn't actually any confirmation of Kubo having been rushed. However, it's fairly obvious that based on how much he had built up toward the fight, Kubo had intended to have it last for at least a chapter or two more. With the exception of Kensei (whose vanishing during the FKT arc was probably also Kubo being forced, since he confirmed that the arc was already stretched beyond what he wanted) every Bankai that has ever been revealed in the series has been explained properly and fairly thoroughly. Minazuki, however, wasn't. On top of that, he condensed Unohana using her Bankai, a flashback to Unohana realizing Kenpachi's potential, and the end of one of the most hyped fights thus far into one chapter. That's not like him, not by a long shot.
