Thanks for alerting us.
If it was a few dozen lines I'd wave it through. But this is a 1800-line patch. I've commented on the MR.
As to process, it sounds like a library issue, but it affects GHC's code base, and quite substantially so. So I wonder if it might actually be salutary to write a proposal. At the same time I don't want to appear to discourage, still less sandbag, this as a contribution to GHC.

Hi GHCSC,
Before this committee existed, Alex Vieth submitted #11342 (https://gitlab.haskell.org/ghc/ghc/-/issues/11342https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgitlab.haskell.org%2Fghc%2Fghc%2F-%2Fissues%2F11342&data=02%7C01%7Csimonpj%40microsoft.com%7C23e434cc47e14de9ce4708d85c0b3f5b%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637360551746873922&sdata=NnGZFdf3tP5F93OiKvcZmYrQrRykZ4wixXQ%2FU9xiFIA%3D&reserved=0), requesting a kind `Char`. Serokell has now provided a patch, !3598 (https://gitlab.haskell.org/ghc/ghc/-/merge_requests/3598https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgitlab.haskell.org%2Fghc%2Fghc%2F-%2Fmerge_requests%2F3598&data=02%7C01%7Csimonpj%40microsoft.com%7C23e434cc47e14de9ce4708d85c0b3f5b%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637360551746873922&sdata=sM%2BmZ%2FXPGQ8RHxlioFtiUpcw3FBfrQogfnIEudEqhqM%3D&reserved=0). The chair of the CLC has signed off on this patch (https://gitlab.haskell.org/ghc/ghc/-/merge_requests/3598#note_300231https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgitlab.haskell.org%2Fghc%2Fghc%2F-%2Fmerge_requests%2F3598%23note_300231&data=02%7C01%7Csimonpj%40microsoft.com%7C23e434cc47e14de9ce4708d85c0b3f5b%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637360551746883879&sdata=XHCCmKT1i0DEfFBldTtKlQdHtDt%2F4s%2BuSlMt4HhAE%2Fk%3D&reserved=0). But I feel we should, too.
What is a good process here? Just debate amongst ourselves? Post a GitHub Issue to call wider attention? Post a proposal? Merge without debate?
Richard
