+1, as I don't see a downside. However, I don't think this change is a sufficient change as long as stack traces are only available for profiled builds. I still wish something like rewrite-with-location[1], which even addresses explicit stack traces directly[2].
IIRC, last time that feature was brought up for discussion, it stalled due to disagreements on the right design.<u></u><u></u></p>

https://ghc.haskell.org/trac/ghc/wiki/ExplicitCallStack/ImplicitLocations</a>, see #9049. It’s simple, non-invasive, and predicatable. It does need someone to implement it though. Simon Hengel is thinking about implementing it. (He is the one who also
suggested “rewrite with location”).<u></u><u></u></span></p>
