Sure, but his proposal is to move in the direction of *less* debugging
information.

If I could have the traceback continue into the C code and tell me the
line of C code that raised the exception, *that's* what I'd choose.

The debugging information barrier of the C–Python boundary is a
practical limitation, not a desirable one. I think those barriers should
be as few as possible, and don't agree with enabling more of them.
