Oh, because of their perennial willingness to change a released standard, with no way to identify revisions.  The C++11 of today is not the same as the C++11 of 2011, for example.  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."
The DWARF committee has the decency to provide a new version number when the interpretation of some attribute changes.
