I wouldn't be too sure of that. You need to consider who the targeted audience is for your feedback. I would guess the organizers of the coming year(s). So a postmortem would make most sense on the wikimaniateamwiki (yes, another internal wiki). I had in 2008 for example much use of the program committee postmortem documentation of 2007 in Taiwan - even though it was not public. As long as it reaches the right people. It is a lot of effort to make a public version in some cases, and then I really dont see the point of obligating people to make such a version - especially if the consequence of that is that the chance they actually will do that, decreases.

The discussion can happen in private, but the results need to be
public or there is really no point. The people discussing it will
probably never run a Wikimania again, so they don't really need to
know what did and didn't work. Anything that needs to be confidential
can be redacted from the public version and the un-redacted version
only shared with people that specifically need to know (teams
organising future Wikimanias, and maybe those bidding to organise
them).
