Change 218897 had a related patch set uploaded (by Dereckson):
Deploy Flow on [[fr:Projet:Astronomie/Porte des étoiles]]

https://gerrit.wikimedia.org/r/218897

Some extra notes:

• This allows a real test for experienced contributors on fr.wikipedia, as currently, the system were only deployed on a test page and on the « forum des nouveaux » page, a place for newcomers (a little like the en.wikipedia Tea House, but less formal).
• Flow is already deployed at project level on en.wikipedia (Breakfast and New Hampshire), which is more useful to test and get issues than other talk pages less used by experienced editors.
• Participants of the project are aware of the experimental nature of Flow, of the existence of small issues, and of their responsibilities as testers, and accept them.
• The participants expect this change to be reverted if the system doesn't work for them and solutions couldn't be found.

@Quiddity, @DannyH: There's a patch to do this with a config change. Do we still do that or does it have to be done on Special:EnableFlow? If so, who has the right to do that on fr.wikipedia?

It should be done with Special:EnableFlow. Unfortunately, I just tried that, and got a bug. I'm going to see what I can do about that...
