Comment (by vanessamchale):

 >Stack is by far the most popular way to install GHC

 I don't think that's true.

 > stack is far more popular as a build tool than cabal

 You can use the system GHC with stack, as mentioned above.

 > indicate that this problem is a show stopper for 8.4.2

 This is not true.

 If for whatever reason they are constrained to using stack on Ubuntu
 without using the system GHC, they can use the latest LTS snapshot.
