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.
CEF was designed to support offloading the RP.
