Now, I am the one, who does not understand the fuss. 

I actually thought we went one step further down the right direction. At least in the direction that most of the people here wanted this discussion heading.

To me this reads like "Canonical won't pay anybody to program a moveable launcher, but will accept a well written patch which allows the launcher to be placed at the bottom of the screen". So if all design requirements are met the new option for the launcher will be accepted. At least this is how I understood it. 

I do not know why anybody would now want to leave the Ubuntu train. Nobody could expect Canonical to invest money into a development when they see other, more pressing, features to be implemented. 

I was complaining here, because I thought that "won't fix" means that the also will not accept any patches. But with this new answer I am pretty pleased. I am no programmer, so I am afraid I cannot implement the code for a moveable launcher myself. But still this gives me hope that there is the possibility of a moveable launcher. That is all I wanted. To hear "it could be feasible and we will accept a patch, if it is well written". 

@Maarten Kossen: 
Don't you think yourself that you sound somewhat exaggerated and hypocritical?  Look at the comments of this article: 
http://www.omgubuntu.co.uk/2011/11/ubuntu-desktop-designers-clarify-on-configurability/
there are tow main elements that permeat all comments 
a) more configurability is great  (there are not very many comments stating that they want the number of options stay the way it is)
b) many people state in the comments that Canonical/Ubuntu should learn to do PR work. And I have to agree with this. If this all was already on the agenda for a long time then why did not anybody say so month ago? Much of the fuss about many of the aspects in Unity would have been avoided. I, personally, am annoyed by the unmovable launcher, but I could have lived with it if I had thought that this would be one of the few things that would not be configurable. But instead it all appeared as if there would never be much space for configuration at all. So seemingly I was wrong and there will be a couple of options to configure the system. But many discussions and much of my frustration could have been avoided by some simple statements to the public (or to the community). 
You say yourself you would prefer the launcher to be movable. So you cannot be entirely content with the system. I look at my own work and see that there are many things that I can improve. I do not applause myself because I did not make much errors today or yesterday; I simply look for those things I can improve. Real approval or praise is never uttered loudly, it is the lack of complaints. In a music concert you do not applause after every  performance you can do so after everything was finished and everything found your approval. If someone needs  approval or applause for the things he does, he knows he does it wrong. 
It is hypocritical to thank somebody for his work, though, in the same comment you state that you would prefer that something would be improved  (like having a movable launcher). You thank for something which you do not really like. So please do not brown nose and please do not call anybody here a drama queen. 

To be critical about something and pointing out errors that is always more productive than just saying "oh wonderful, that is great". Finding something great and thanking for everything never brought us forward. Do not look at those who congratulate you for your achievements, look at those who criticize, then ask yourself if the criticism is correct and if there is something which could have been better. That is the reason why we have grades at school which range from A to F. 

I am content with the most recent development. I certainly will not thank for this development, especially when I look back at the recent 12 month and the whole discussion in and on this launchpad page. To be content is the most honest thing I can do. Especially when looking at the mentioned  OMG Ubuntu article.
