GHC.Internal.Exception.Backtrace.Backtrace not exposed?

Maybe I'm missing the obvious, but with the new exception annotation mechanism, how would I access location / stack trace information in a structured manner?

Am I expected to parse the output of displayBacktraces?

N.B. this is not some exotic use case. Every piece of software that needs to correlate exceptions with source code locations needs this (e.g. everybody who wants to send data to sentry, rollbar, airbrake, ...)
