So, we should remove the changelog entry and instead add a changelog entry to
19x explaining the breaking mangling change.
I think we've missed the 19.x cycle for this because it involves an ABI break
(and final goes out in less than a week, which is not enough bake time for us
to land it before 19.0.1):
