"especially given that you can essentially use it as a "functionally enhanced java" as it's not a hard-FP language like Haskell"

I'm not sure if I can call this "the Haskell community consensus", but a lot of the Haskell community finds Scala too complex to be worthwhile. They find it introduces a lot of complexity above and beyond Haskell, but at the same time, fails to take proper advantage of it and the result is quite dirty, full of special cases, and consequently hard to reason about. So you get a lot of the costs, perhaps even more costs for compliance than a Haskell code base, but you get fewer benefits.
