Comment:
To summarize a bit:
- The latest patch should cover all concerns raised so far: it handles
specialized querysets such as `ValuesQuerySet`, doesn't break pickling,
cruft-free methods definitions, sane defaults (no private or magic
methods), a mechanism to opt-out or force-in certain methods and it's
robust enough to sustain the complete Django test suite while replacing
almost 90% of `Manager`'s public API.
- We settled that deprecating legacy proxy methods is out of scope for
this ticket while acknowledging that it's desirable in the long run. We'll
open a dedicated ticket once we land this feature.
- Since we are '''not''' deprecating the legacy methods, we need a
dedicated test suite.
- 1.6b1 has landed, so we can resume work targeting master.
Where are we in term of consensus? I'll turn this into an RFC patch as
soon as I get a green flag on the implementation.
