The sha1 changings are only a problem if you published the commit and
someone started working on it. Because if you change it, basically you
remove the oldcommit and create a new one. People that started working
on it will have to repair their tree.

But if it's something that stayed on your computer, it is not a problem
to rebase it.

By the way, my 'mildred' branch is constantly rebased these days, but I
don't expect someone to use it, so I don't think it is a problem. And if
someone used it, they could always rebase on the rebased version of my
branch.

It makes things clearer, especially when we have many branches merging
together. Having non-essential merges like thig complicates the graph
needlessly.

Then, it makes things more difficult for git bisect (run a bisection to
discover a bug):

Why not,

But for very small changes, it would make it slow to commit changes. And
it would require someone to be available constantly for such requests.

While I agree that for some big changes this would be good (provided the
person answers quickly), I don't want to complexify simple cases. And
take Damien for example, I don't think he needs anyone permission to
modify his eclipse plugin.
