Does that mean that Hackage provides a package set that doesn’t work
well together? Or is it a defect in our updater?
I think it would be great if running “guix refresh -t hackage” would
give us a package set that works together, provided Hackage does the
necessary QA. (I thought it did because Nixpkgs imports all of it
wholesale AIUI.)

Agreed, we need a Haskell champion to take care of this—not necessarily
to do all the actual work themself, but rather to keep track of what’s
lagging behind, what needs to be done, and to coordinate efforts. My
impression is that people have been willing to help on this in the past
but didn’t necessarily know what upgrading would entail.
If you’re reading this and feel familiar with Haskell’s infrastructure,
please don’t hesitate to chime in!
Thanks,
Ludo’.
