That doesn't address the question of why the deprecation is added
to a bug-fix release.  Normal policy is deprecate in the current
feature release and make the change in the next feature release.

Is there a reason why the normal deprecation process should not be
followed in this case?  It being a not-likely-to-be-encountered
in-the-real-world bug could be one such reason, if the release
managers agree.
