The idea is that you generally always have to do extensive validation when
accepting user input through a form. These validations could require
additional database queries or other somewhat expensive lookups (especially
with validate unique).
However if you are loading data from a trusted source, e.g:
for row in your_csv_file:
instance = Model(**row)
instance.save()
Then there is no need to call that potentially slow full_clean(). There is
not much value in slowing down all .save()’s needlessly - the developer
should know when it’s appropriate to run validations and can run
full_clean() when needed.

So the validation is cheaper when performed by ModelForm, as opposed to the
Model?
