I vaguely recall it was discussed but not considered an important

Not immediately. But by now we've had two alpha release already. Some
stuff *does* change between alphas. But in general we need to stem the

I think you need to provide a lot more motivation than a 5-line email

To be brutally honest, your recent attempts to open up various closed
issues have wasted a lot of cycles everywhere. I'd rather focus on
moving forward with things like UserDict.
