As I said, none of my post is to exclude that they can't do it better in the future. Consistent visual design is important, and people would absolutely tear a Mario game apart at the seams if sections requiring precise platforming had a bunch of collisions you couldn't anticipate or that didn't follow a set logic, so I agree with you that what you see is what you should get.
I'm just also coming at it from the other side and saying that, regardless of what you see, you are still going to be learning the rules of the jumps and where to aim each one, so fundamentally at a base level it doesn't change anything. If you want to get it done it's all going to come down to rote repetition, so rather than fighting against the way it's designed it's better to get comfortable with those collisions since it's not like they change each time anyway.
I'm also totally not against them cleaning up the tower a bit and making some of those sections more consistent, such as the part where you have to jump around the north side of the tower to the east side, or the final jump at the top which is probably the worst offender.
There's always a Roegadyn in a robe blocking everyone's feet. Every time.
