I've discovered magic spell in Universum.Base module:

https://github.com/serokell/universum/blob/d14925085b1fc7037f25542618b931d22dcf13b4/src/Universum/Base.hs#L104

We should research on this and discover whether it useful or not.

HasField is not commonly used at the moment. This issue didn't receive feedback. So probably nobody understand the purpose of this type class well enough and can recommend everyday use-cases. But I like exporting Type for * kind. Personally I started to like writing a :: Type more than a :: *.
