There have been various requests for this for a while. See https://github.com/flutter/flutter/issues/96283 for an example. This has become more important with dart2wasm builds in the mix, as the profiling versions of the dart2wasm builds are a lot less debuggable than the debug versions. Most of this is already wired up so it just requires taking out a few explicit checks for it and making sure that we compile with the right optimization levels when compiling debug.
