iirc there was a community effort 2 or 3 years ago, but now ghc has changed enough that the compiler and runtime parameters seem to need re-tuning.

There's always room for 2 or 3 Haskell programs per task - not necessarily The Good, the Bad and the Ugly - but you'll already find the cliched example of a faster more convoluted Haskell program and a more concise but slower Haskell program.

(Idiomatic code? Aren't there idioms for writing fast Haskell too?)

These are tiny tiny programs - when those compiler optimization improvements arrive re-write the programs to take advantage of them ;-)
