Had a discussion with @bgamari today on #ghc IRC channel, there's a design that would allow to collect all stack traces with DWARF, but it needs to be implemented in base first.

For the record, this discussion resulted in ghc-proposals/ghc-proposals#330. Thanks to @domenkozar for providing the motivation to address this.

Additionally, this is tracked as GHC ticket #18159.

Looks like we're waiting on https://gitlab.haskell.org/ghc/ghc/-/merge_requests/6797

[bgamari]

We are currently waiting on haskell/core-libraries-committee#164, which would allow me to proceed with https://gitlab.haskell.org/ghc/ghc/-/merge_requests/8869. I am very much hoping, although not optimistic, that we will be able to get this done for 9.10.
