Empowerment takes the idea of delegation much further than has traditionally been the case.

has traditionally been的主语是什么？为什么可以省略？

has traditionally been the case
= traditionally has been (taking) the case
我感觉这里的 traditionally 的用法有点像 'last years have seen ...' 里的 'last years'

the case
= the idea of delegation

个人观点，还请批评指正
