It was a particular area where developers seemed, to me, to express more confidence in HG, over git, at the same time expressing that this is indeed likely to be a difference between the two systems that will not persist indefinitely.  I also saw, as it was discussed, a number of developers chime in with their real life experiences with both systems, and some give and take as to which of those experiences validly reflect accurate understandings of the two.  Particularly, I saw _at least_ 4 emails responding to Felipe's ideas and concerns, including some research done by a developer in github (I think it was github) to be sure that we all had an accurate understanding of git.

The topic is introduced to the mailing list in a way that makes it clear to me that the discussion in fact started, no doubt in either irc or in the muc conference room, sometime prior to that.  I see participation from most if not all of the active developers, and even a few, like myself, who are inactive but still interested.

If _any_ developer, cpw, or summer of code contributor felt that there was more to be discussed, concerns not yet considered, I am equally confident that any migration would not be considered final until some sort of consensus had been reached.

This is what I mean by analysis:

There's nothing like that.

I have read all the mail archives, and I haven't seen a _single_
reason why hg was preferred over git. The closest was that John Bailey
doesn't like git branches, but when I explained why git branches
actually make more sense, John conveniently decided to stop the
discussion.

So no, I don't think the possibility of using git has actually been
considered at all.

Consensus, yes. Explanation, no. In fact, most of the votes were
casted _before_ the discussion even finished, many before it even
started. It's like no analysis was needed.

Read John's mail (with two votes communicated to me off-list):
