I'd find that a bit counterintuitive. To me, --release is an alternative for --debug. Debug implies debug stuff is in there, therefore the alternative removes it.
But I do find it useful now and then to have debug symbols in production, so that monitoring and telemetry gets some context. But to me, it's rather logical that I need to add this to the build.
I would, however, love it when it's trivial to get these symbols set up external.
