@brettcannon I was thinking the other day, that if PEP 665 got "lukewarm" reception, cause it was focusing on wheels, and reproducability and later on add src (that's my takeaway from the thread), why not do the same proposal but inverted, with src/dist, sort of standarized "requirements.txt" and wheels and reproducibility later on? (I know it's not your use case, but might be a way to just move on with the whole thing? As far as I could tell one wouldn't step onto the other?) @kaleissin@dreid
