Quite. Why expend the effort on a development that will cause unnecessary
Generally speaking, end-users will live their lives in blissful ignorance
of [Pending]DeprecationWarning and should be allowed to do so. When a
developer wants to migrate them to more recent versions of Python there's a
chance that warnings will be enabled and examined, but it's by no means
I suspect the real value of the warnings is so that the dev team can shrug
their shoulders when someone complains a feature has gone missing after ten
years in deprecated status. This is the price of having them normally
silent, which is certainly worth any trouble it causes by refusing to
hassle innocent non-developers with warnings they can do nothing about.
