But even for failing cases, changing the expected output changes the
functional specifications for the code. That's never an obvious
change.

If libiberty and libstdc++ shared sources for the demangler, and there
was an agreement in place to keep them in sync, and the testsuite
change was done in conjunction with a source change, and it was all
discussed and approved for libstdc++, you'd be right.
But it's not.
