Not really. There existed distributed fastswitching before DCEF came
along. It might still exist. CEF was developed to address the issue of
route cache insertion and purging. The unneccessarily painful 60 second
interval new destination stall was widely documented before CEF got
widespread use. The "fast switching" approach was also particularly
painful when DDOS attacks occurred.
