Hint `case` instead of `let` outdated in favour of bang patterns?

Is the advice "case instead of let" in the user guide still up-to-date? https://gitlab.haskell.org/ghc/ghc/-/blob/ad28ae41206e3a8b483b067a8e3333df445010b6/docs/users_guide/hints.rst#L175-190

A less contrived example shows the use of cases instead of lets to get stricter code (a good thing):

        f (Wibble x y)  # beautiful but slow
              = let
                    (a1, b1, c1) = unpackFoo x
                    (a2, b2, c2) = unpackFoo y
                in ...

        f (Wibble x y)  # ugly, and proud of it
              = case (unpackFoo x) of { (a1, b1, c1) ->
                    case (unpackFoo y) of { (a2, b2, c2) ->
                        ...
              }}

Wouldn't one use bang-patterns instead nowadays, rather than uglifying the code?
