New question

OG say : In D and E, the preposition "for" is less idiomatic than “of” in expressing necessity.
        

But Longman say :

necessity for
            

He emphasized the necessity for good planning and management.

the necessity of (doing) something
            

This illustrates the necessity of keeping accurate records of your work.

Many teachers are now questioning the necessity of formal exams.

Why "necessity for" is less idiomatic ?

暂时还不是很理解，当作固定用法吧，类似的词还有importance和need
