Am I the only one thinking that disabling deprecation warnings by default
(2.6?) was a bad idea?
It's particularly counterproductive for library vendors and their users
because the latters have no visibility of what APIs are going to be
removed: they will just wake up one day, upgrade to the next major version
of their favorite lib and have their code broken.
