Comment (by taylorfausak):

 Once again I am sad to see this ticket closed without any fix put in
 place. I am also disappointed in the behavior of GHC developers who appear
 to be breaking downstream tools and making absolutely no concessions to
 them. Needless to say, this entire experience has not been positive. I'll
 leave you with some assorted thoughts:

 - As has been stated repeatedly in this thread, one of the problems is
 that build plans that used to work have stopped working. Anybody trying to
 use a GHC >= 8.2 snapshot with Stack < 1.6.1 will be unable to do so.

 - `integer-gmp` does not have its own bug tracker. As I said when I opened
 this ticket: "I was not able to find an issue tracker for integer-gmp.
 Someone suggested that I open an issue here instead." I asked @hvr on
 Twitter where to report `integer-gmp` bugs and he said I should report
 them to him directly.

 - In my opinion, Stacakge nightlies aren't "unstable". Furthermore,
 knowingly breaking them is at best inconsiderate and at worst hostile.

 - It did not take Stack 5 months to support GHC >= 8.2. I have been using
 Stack with GHC 8.2 since the release candidates. Stack's support of GHC
 8.2 was broken by @hvr's package uploads on December 4.

 - `integer-gmp`'s Cabal file has been updated on the `ghc-8.2` branch of
 the GHC repository, but it has not been updated on the `ghc-8.4` branch.
 Perhaps we'll end up in a situation where the repo doesn't match Hackage
 again.

 I find myself once again repeating the crux of this ticket:

 > it's frustrating that a core library is using a bleeding edge feature
 for basically no reason

 I haven't seen anyone even attempt to explain why `integer-gmp` needs to
 use `^>=` bounds. The argument seems to be that it can, so why not? I
 think "not breaking other tools" is a pretty compelling reason not to.
 Apparently GHC developers think breaking other tools is an acceptable
 price to pay for saving 8 characters in a single Cabal file.
