Upper limit was once necessary to support ghc 8.0 (https://travis-ci.org/github/mtth/tracing/builds/764494212) - but now seems to block stackage nightly. Not really sure what ghc versions should be supported - travis-ci build is outdated; and github action is using ghc 8.6.5. However this is another story.
