Hi all, Here are my two cents. Disclaimer: I'm another Hackage Trustee and I care about this for the same reason Oleg does (specifically: the transitive closure of `diagrams`)
Would it be worth trying to consolidate similar data structures and have Chart + diagrams migrate to Only [1] (which is up to date)?
I have suggested that here https://github.com/DavidM-D/indexed-list-literals/issues/1 Definitely in the longer term, I'd rather see a move to the Only package. But in the short term I'd find it much easier to get current packages working on GHC 8.4 if OneTuple supported 8.4. Oleg's changes look sensible to me, and adding a co-maintainer seems reasonable given that the last release was nine years ago and the sole maintainer seems uncontactable. My preferred course of action would be to add Oleg as a co-maintainer, and move downstream packages to `Only` over time. I intend to participate in the latter. Cheers, George
