The key difference between the last two: * DeprecationWarning: the decision has already been made, you have little chance of getting the deprecation reversed * PendingDeprecationWarning: full deprecation is being considered, now is the time to get in touch if you'd like to avoid full deprecation

Are people actually aware of this difference? Personally I am (was) not.

Antoine.
