Comment (by bgamari):

 Why I don't have a terribly strong opinion here one way or another, here
 are my thoughts,

  * I agree that, to a GHC developer, hiding paths by default is on the
 whole a small inconvenience. There is a certain convenience to pulling
 paths out of `ghc --make`.
  * I also agree that these paths are just noise to most users
  * However, I suspect that relatively few users are actually exposed to
 this noise at this point. Afterall, most users are using `stack` or
 `cabal-install` and both of those now hide GHC's output by default.
  * Even if the user uses a build tool which shows GHC's output (as `cabal-
 install` currently does with `-j1`), there's no reason why the tool
 couldn't pass `fno-show-source-paths` to GHC by default.
  * I really don't think the benefit-per-character-of-discussion ratio of
 this issue is high enough to warrant too many cycles
