2) an option to provide a structured error output in some common

deterministic, and would be of significant benefit if other
compilers/interpreters also provide the same functionality in the same
common format.
Exception instances have a .__traceback__ instance that is used to print the default traceback message. So it has or can generate much of what you request. I believe traceback objects are documented somewhere. Some apps wrap everything in
try: run_app
except Exception as e: custom_handle(e)
The sys module also has an excepthook (1) which can be overridden to customize the exception handling. Note that it does not function with the threading module, however.
