Proposal: deprecate Prelude.read

[David Feuer]

If it doesn't give a call stack, we can fix that. While I avoid using
it myself, and I think it's much better to use (at least)
Text.readMaybe, I'm not convinced that the breakage to existing
educational material is worth the benefit of actually removing it.

Adding deprecation should not break anything substantial because Hackage rejects -Werror (application code using -Werror is likely to experience a lot more breakage anyway, and I'd say it's their fault if it fails to build due to a use of read along with -Werror).
