Luckily, all build failures where just related to type checking changes in GHC 9.0 (and maybe base changes?), so we can just use GHC 8.10.7 with the Stackage version of packages and keep Yi working. I feel like we dodged a bullet here, as upstream maintenance doesn't seem to be too proactive these days.
