I also updated the wording to mention the points that have been discussed and simplify the wording a bit (less repetitions, less C-side stuff). I didn't update the implementation yet, but technically the TL;DR of this new iteration is that it brings nothing new: it's only a refacto of the presentation. This message starts a new discussion period. Cheers, Nicolas
