The "how" part of (b) is already mostly covered by http://symfony.com/doc/current/cookbook/configuration/override_dir_structure.html

• src/AppBundle/Tests/... -> tests/AppBundle/... ?

I start with the book chapters now.

Unless I missed something, the referenced PRs above this comment fix (a).

The code has been updated now for the new structure, thanks to Wouter! For the explanation of the changes... I think that should maybe be at symfony-standard - that repo is missing an UPGRADE log currently for 3.0, which is the most important. I've covered the changes for KnpU here: https://knpuniversity.com/screencast/symfony3-upgrade/new-dir-structure we could repeat that in teh docs, but it seems wasteful.
