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

Hence the last one only showing up to those folks that are running
automated tests or otherwise enabling all warnings.

Cheers,
Nick.
