That is pretty much how things are intended to work on a filesystem
and is not limited to Git.  Your arrangement, contrary to what you
said, does not "ensure the user running the command is not able to
edit but has read access".

    mkdir newdir
    chmod +rwx newdir
    >newdir/file
    chmod a-w newdir/file

would not forbid you from doing

    rm -f newdir/file
    ehco new >newdir/file

In other words, if you allow your user to write to a directory, you
cannot forbid the user from creating and removing files in it.
