Ticket #1216 suggests a release-based deprecation policy that is not graded and over 1 release: release N, add DeprecationWarning, release N+1, remove the functionality.
As a user, I don't see much difference between a PendingDeprecationWarning and a DeprecationWarning. Or between a DeprecationError and the code being removed. Simple is good.
A PendingDeprecationWarning is not visible by default, so users of an application won't be inundated with DeprecationWarning messages they can do nothing about; but a developer can turn them on in order to check if his application is using any deprecated APIs. -- mithrandi, i Ainil en-Balandor, a faer Ambar
