Comment (by nomeata):

 Before putting stuff in `base`, maybe start start a library `ghc-stack-
 utils` or something with this (and possibly other combinators)? This would
 allow you to experiment more freely, users can use it with old versions of
 GHC and we see which combinators are actually useful. We can add a
 reference to this library in the documentation for `HasCallStack`, so that
 people can find it.
