One thing almost all Mega Man fans noticed when the Mega Man 11 demo came out was a change in how boss shutters worked. For every other installment in the Mega Man series, you could jump through a boss shutter and hang in the air as the screen transition. Mega Man 11 removed that feature, and fans have been wondering why ever since the discovery. In an interview with Game Informer, producer Kazuhiro Tsuchiya gave an answer.
According to Tsuchiya, since areas in the game are, "connected by horizontal shutters placed in the floor," they "unified" the movement to have things make sense. Tsuchiya says that, "if players were to slide onto the shutter, they would then fall into the area below in the same pose, which would be unnatural."
In other words, because there are shutters on the floor now, they had to do away with the hangtime for boss shutters. I don't know about you, but I think that's a pretty bogus explanation.
