Not so. It's how to break a fall. Better to break a fall than break yourself. How to harmonize with the ground.
Let me ask you this, where would you find experts on break-falling?
It would be a place where people need to harmonize with the ground because falling is part of the job. So outside of Aikido you can find stuntmen, comedy actors from charlie chaplin to jackie chan, etc.
They all learn how to connect with the ground properly when falling, no form, basic rules of such. Form comes later and rolls are later on that list.
So a break-fall is how to land comfortably. Most landings from falls you can't roll from so most break-falls do not include rolling.
I know a stunt man or two actually. While I haven't taken stunt "classes" from what my friend tells me it isn't all that much different from what we do in Aikido.
If one is performing a roll correctly they are connecting with the ground properly!
If it is a breakfall then no, you are not rolling. The alignment of the body however is identical with the exception of a backwards fall.
Either way repeated practice is the only way to prepare.
