Comment (by 4e6):

 Ok, I [https://github.com/4e6/webapp-template-hs/tree/simpl-tick-factor
 pushed] the update that removes almost all external dependencies. With
 this update, I was able to build the project with latest
 ghc-8.3-start-1211-g82b77ec375 (version by git-describe)

 Interestingly enough, ghc-8.3 doesn't show the presence of the bug. It
 means that the regression was fixed after the ghc-8.2.1 release.

 I also updated the
 [https://gist.github.com/4e6/5ef65efdb309daa373a928ec36404fd7 gist] with
 ''-ddump-simpl-stats'' output for all three ghc versions. Total ticks
 number for ghc-8.3 is similar to ghc-7.10.3 value.
