Thank you ! I missed quite a lot !

[DudeNr33]

We have two different milestones currently (3.0.0a6 and 3.0.0.b1). I saw that the other pyreverse PR (for the --show-stdlib option) was targeted for 3.0.0b1, so I set it here as well.
Do you want to release 3.0.0.a6 first before I merge?

[Pierre-Sassoulas]

3.0.0a6 is enacting the deprecations, there's some work to do still, but life goes on as usual, we're just going to release all enhancement / false negatives / other breaking changes as they come naturally. (Also this MR feel like enacting a deprecation.
