Multiple types of arahant: a later development? Is the Pavāranā Sutta corrupted?

Roderick Bucknell wrote a very interesting article, not sure if he ever published it, about the various elucidations of the path. He had a very interesting idea about sīla samādhi paññā, countering the usual analysis of the 8fold path, and saying rather they relate to the 10fold path, having sīla as:

• sammā-vācā
• sammā-kammanta
• sammā-ājīva

Samādhi as:

• sammā-vāyāma
• sammā-sati
• sammā-samādhi

Then coming to the 2 fruits of the path, paññā as:

• sammā-ñāṇa

And vimutti as:

• sammā-vimutti

His analysis seems to me better than the traditional one (which divides the 8fold path into those 3). I’m not sure if the traditional one even came from the Buddha - seems it came from a nun, and perhaps rarely mentioned in the EBTs apparently (can anyone confirm?)… perhaps a later adaption?

I made a post discussing the Bucknell Article and the Sutta involving the nun: Another interpretation of the Cula-Vedalla sutta (MN44)
