Hi, I'm the author of the article. I think you're right, and I think Haskell delivers on your definition of "better." I chose to try Haskell because I've been through a lot of agonizing maintenance work and I'd much rather do it in an environment that has mandatory, pervasive static analysis and tests that are by default isolated from all possible nondeterminism. We don't have any 8-year-old Haskell yet, so I can't fairly compare it to refactoring our PHP codebase, but I have made a few sweeping changes to our 60k lines of Haskell over the past year and a half. It tends to be mostly effortless, no matter how much code needs adjusting.
