Well, I'm surprised some dojo's do not practice breakfall in all it's forms.
IMO, all possible ways of falling to the floor need to be examined.
I think each one of us needs to be able to fall safely from any action. Self preservation is paramount.
For me, training with beginners is the ultimate demostration of this. As a beginner myself once I remember how my experienced partners had to adjust to and accept my limitations, this has stayed with me since then.
Wherever I train in the UK, breakfall is considered important and sometimes practiced in it's own right.
