You will need to install an svn client when you want to use svn. Trac is not a
VCS and the upload of patches as attachment to Trac tickets for me is a
missuse of tickets. Anyway, of course you can also create patch files with
git, upload them to trac and apply them somewhere else. The various commits
will be available in the resulting branch as well, so the result is identical
to using git pull.

1. git push/pull is usually a lot faster.
2. you can still upload patches to Trac, if you really like it so much.
3. instead you can also create tickets with pull requests from servicxes like
e.g. github or your own webserver.
4. someone, who is not the maintainer might like your patch better than him.
He can apply it to his repository without disturbing anybody else. He can
rebase it on any other changesets the maintainer puts into his repository.
5. after you submitted your patch you can go on working on the same repository
without having to waint until your patch is applied to a branch in the main
repository and you can svn update.
6. The maintainer can experiment with your patch. E.g. he might like it
mostly, but fix a small part, before he pushes it into the main repository.
Then the fix is in the version history with his name, while your changes are
in the history with your name.

It simply opens a huge ammount of more options.
