I find MF to not be forgiving...scanning is a little more difficult because dust shows up more easily, even straight from the lab wrapped in plastic. I need to wipe down each negative with a microfiber cloth, even when using digital ICE on my scanner. 35mm does not require this.
I am puzzled by your perception...dust is the same size on MF as it is on 135 format film. When the dust gets scanned, it occupies the same scanner distance regardless of the area of film around it. When the image is printed at 8" x10" (or 8" x 12" size, the image and the dust is magnified 8.5X from 135 format, and the dust is magnified by 4.7X from typical 645 format...the dust becomes apparently 1.8X larger as seen on the 135 format scan's resultant print!
Comparing 24mm x 24mm section from 135 format vs. 56mm x 56mm section from square medium format, the magnification advantages of medium format vs. 135 format are even greater than 645 format...2.34X advantage for medium format in the apparent size of dust on the 8" x 8" print.
I understand that mefium format has more film area to gather dust, So cleaning film is more arduous because the larger area has to be cleaned. But any dust is less apparent after magnification to final print size.
