Apart from variable patch ordering all of that is true of all DVCSs.

You can emulate darcs's patch re-ordering in git if you put each
independent sequence of patches on a separate branch. Then you can
re-merge the branches in whatever order you want. This is a fairly
common git workflow.

It is normal in git to keep a pristine branch for each remote repository
that you pull from - git sets these branches up by default. There can be
many remotes in a git repository.
