Certainly
That is my understanding of what I am attempting to do anyway, going through the sagathavaggasamyutta and trying to see if we can reasonably infer that the atthakavagga and the paraynavagga are likely representative of an earlier, less institutionalised and less concerned with donations period in the development of Buddhist texts as compared to it, which would then be indicitive of a later, scholastic, urbanised text. I see no better nor more principled way of answering the question in the OP:
Than what I am trying to do here.
The argument from the prose, that SN/SA as the earliest Nijaya/Agama stands or falls with the aggregates doctrine as the earliest doctrine, and that argument is made by me in the thread:
The poetry I have always been wary of picking up, but am doing so now as it seems to be a crucial part of the “argument of Yin Shun” which I meet with via proxies around this discussion and look forward to examining in the original once I have finished my appraisal of the poetry, it being, after all, an integral part of any discussion I may enter into directly with (the ideas of) Yin Shun.
