From oldest to most recent:

https://github.com/coq/coq/pull/313 (Scoped options) Emilio suggests that this needs to be discussed with a small group, around a computer so we can have a closer look to the way liboject is working.
https://github.com/coq/coq/pull/400 (Reducing temporary allocations in CClosure) Pierre-Marie needs to convince Guillaume of the importance of his patch, and Emilio that this has nothing to do with Flambda.
https://github.com/coq/coq/pull/616 (Make some keywords into normal idents) Gaetan will lead the discussion (last time this was discussed, he was not here).
...
https://github.com/coq/coq/pull/1003 (intros '(x,y)) The debate is about "syntactic pollution". I guess the people that are rather against the merge of this PR (Pierre-Marie, Maxime) should explain their viewpoint.
