This doesn't feel intentional, since it completes the expected next section with one play, but you can do the bottom left section with just mid air jump and dash, you don't need to remove the blues to reach it and the only part that has blue(as I recall) is just the beginning, which you can just double jump from the ground to do(with a bit of difficulty).
Also checkpoint disabled didn't seem to work on that section, but now it is? Could be it didn't work before I disabled blues, but I feel like it didn't after I disabled blues once and every other time it does work so idk.
