Among other things, this will cause programs that declare instances against these types to stop compiling if they do not enable the FlexibleInstances extension.
As I noticed in a CLC mail thread(https://mail.haskell.org/pipermail/libraries/2018-September/028975.html), no code from Hackage derives such instances currently. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15622#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
