This is basic revision control, everybody (else) understands this.  I mean, if we found a bug in Clang 8.0.0, we wouldn't overwrite the archived 8.0.0 to fix it.  But that's effectively what the C++ committee does with its "defect repair."

Ah, you're referring to the C++ standard defect report process. Fair enough. Though it seems a bit out of place/unrelated to this discussion. I didn't intend to suggest that DWARFv4 should be retroactively changed - sorry if it came off that way.

Happy to have a separate discussion about the C++ committee process some time.
