if you just want to transition everyone on a project from svn to git then you don't need a git-svn server, you just need a translation tool

what a git-svn server gives you is the ability to have some people use svn (becouse 'git is too complicated') while others use git.

think about sourceforge as an example. they only want to provide one version control tool, they started with cvs and are migrating to svn, but if they could put in a git server and git-svn server and support both.

think of it as 'one version control server to rule them all' (and then encourage people to do git-hg-server, git-arch-server, git-darc-server, etc)

as far as I can tell (with the exception of recording explicit renames) the git functionality is a strict superset of all the other version control tools, so it should be possible to emulate them with git. svn is just the biggest bang-for-the-buck in terms of number of users.
