I think there is something else wrong if someone is using
code with deprecation warnings in a production setup.
The deprecation warning should never show up on a production
server because you have to make sure that you don't use
deprecated code. That's the only goal of the deprecation system.
Your reason says that you like to use packages
with deprecated code in a production setup. On the other
side developer which take care on deprecated code can't be
sure that we use deprecateded code or not. That's not nice.
I was afraid excatly of this use case. Skiping deprecation
warnings is a workarround for official release and use
deprecated code instead of update everything.
A good solution whould prevent to use deprecated code
in a production setup and not only skip the deprecation
warnings because we as developer know that this will
I also think indirect imports are not the same as
deprecated imports. Of corse a deprecated import is
a indirect import but a indirect import is not implicit
a deprecated import. That's just a very ugly pattern
for do something which should be done in another way.
Parsing "# BBB" comments whould be a better solution
for find deprecated imports.
