Which scholars dispute that the Parayana and the Octades are earlier than the four main Nikayas?

[Raftafarian]

The following is from “Buddhist India” by T.W. Rhys Davids and represents his best guess as to the order of Buddhists documents were composed.

APPENDIX TO CHAPTER X
CHRONOLOGICAL TABLE OF BUDDHIST LITERATURE FROMTHE BUDDHA’S TIME TO THE TIME OF ASOKA

1. The simple statements of Buddhist doctrine now found, in identical words, in paragraphs or verses
   recurring in all the books.
2. Episodes found, in identical words, in two or
   more of the existing books.
3. The Silas, the Parayana, the Octades, the Patimokkha.
4. The Digha, Majjhima, Anguttara, and Samyutta
   Nikayas.
5. The Sutta Nipata, the Thera- and Therl-Gathas,
   the Udanas, and the Khuddaka Patha.
6. The Sutta Vibhanga and the Khandakas.
7. The Jatakas and the Dhammapadas.
8. The Niddesa, the Itivuttakas, and the Patisambhida.
9. The Peta- and Vim2na-Vatthus, the Apadanas,the Cariya Pitaka, and the Buddha Vamsa.
10. The Abhidhamma books
    ;
    the last of which is
    the Katha Vatthu, and the earliest probably
    the Puggala
    Paftftatti.

The above table represents the probable
order in
which the extant Buddhist documents of this period
were composed. They were not yet written, and a
great deal has no doubt been lost;’

The Parayana and the Octades(the Eights) appear earlier than the four main Nikayas in the list above. I have seen this position held by many authors. Granted, they may simply have defered to T.W. Rhys Davids , but I have not seen anyone dispute this position other than by people I have encountered here.

My question is, can anyone point me to scholars who hold a different position and where they make their cases?

I already know that Bhante @sujato takes a different position, but I would like to know who else does and where. I am not looking to debate this here. I am just looking for sources that take a contrary position.
