I don't understand why working code should have to change *twice*. I'm fine with the idea that people *actually* relying on the current default will need to switch when the default changes, but making them change once to silence the warning and then again to explicitly select the old default is pretty annoying. If we don't want people to use the default encoding, we should just make encoding a required argument and stop pretending. If omitting the encoding and using the default is intended to be a supported usage, then we should *not* penalise people doing that. Changing the default is a backward-incompatible change, that's enough of an inconvenience. Changing the (behaviour of the) default *twice* is just making things worse.
