Right, and there are plethora of ways to mess up local copies with git.
While it might be possible to get back in a sane state it is extremely
hard. As said, especially with the features everything advertises here,
it gets really hard to maintain something like a mainline git repository.

All I am asking is: what's the point? If it is used as we use svn
currently, why change at all?

So far, I've only heard stuff like: "X is extremely easy to do with git
(If it is done right, and you know what you are doing, otherwise you are
screwed)" (paraphrased).
As others hinted, git should probably seen as a "meta VCS", the workflow
I definitely can see that something like the "linux model" makes sense
for certain libraries. Git was obvously designed for it. However,
whenever I tried to use all those nice and funky features (ease of
branching and merging etc.). I always lost a lot of time because
something didn't work as i expected. After asking people who are
supposed to know the stuff, they told i did it wrong and i should use
another tool in the git toolset. So I did that the next time and ended
up right at the beginning.

Sorry, I really tried to use git. It is all nice if you are alone and
keep developing for yourself and push feature. However, when there are
more people involved, with all kinds of branches etc. I always lost
track and messed something up. Be it that something didn't compile for
others cause merging failed, be it that history was completely borked or
that I myself had the hassle to rewrite history so it all worked out
again. In the end my experience was that all the nice features you are
describing are not worth the hassle and do more harm than they are worth.

Of course, chances are high that i just did it wrong.
So, what i would like to see from you guys is a definite guide to use
git. A description of workflow for both maintainer, contributor and
whatever other role you can think of, and a playground to test that out.
Otherwise, I don't see a lot of value in such discussions.
