If you don't tell it what to push, the command will just update the branches. You can tell "git push" what you want to push explicitly, e.g.

    $ git replace -l ;# to learn what replacement I want to send
    77d5ba8477eb90509e79dbcf63814a3dfdefb906
    $ git push origin refs/replace/77d5ba8477eb90509e79dbcf63814a3dfdefb906

That is between you and other project participants. They may not want to see replacement in their project in the first place.

Assuming that they do, pushing the replacement ref makes the replacing object available in the pushed-into repository, so they will *not* rely on your repository.
