git svn : some feedback and wonder...

hi I'm just toying with git svn.... so I have an svn repository and I do a git svn clone -s http://path.to/my/repository here all is fine it checkout my trunk into master branch

1) when I do a git branch -a, it show 2 branches : master and trunk,
shouldn't it be master and svn/trunk?
2) when I create a branch using git svn branch it create an empty
directory and not as expected a branch from the current revision of
trunk
3) the branch appears in git branch -a without a remote
information.... not easy to track
4) you can't do git branch --track newbranch (where new branch is the
svn branch), since the branch name isn't prefixed by svn/ you can't
reuse the same name
5) why having called dcommit instead of push? it would have been more
understable (more coherent) git svn push would have pushed current
branch on corresponding svn branch and git svn push somebranch would
have do a git svn branch followed by the commits...
6) why having called rebase instead of pull? git svn pull would have
fetched svn/trackedbranch and merged into current branch, git svn pull
somebranch would have merged into current branch the svn/somebranch
(without traking info)

thanks and regards JLM
