Since 4075, settings are iterable

[FichteFoll]

Iterating over view.settings() yields a list of (key, value) pairs. That's a non-standard iteration procedure, but something we can certainly work with to provide a proper dict/MutableMapping interface.

Do we have a roadmap at this point for what dependencies will look like in 4.0?

[FichteFoll]

No, we have nothing at the moment other than they will be installed into the Lib folder and no loader code will be necessary or even supported.
