There's no true default in Fedora anyway. In fact most distros don't have a default anymore. Hasn't been that way for quite a while now, since everyone and their damned dog jumped onto the Ubuntu model of spinning out a separate live cd for every possible desktop option.
This all is to say that any argument for default positioning is really an argument over a symlink on the front page of fedoraproject.org.
If that's true then why not change the default on fedora, such as it exists, from gnome shell? According to you it doesn't matter anyway.
Maybe because you're entire post is bullshit? Thanks, see you.
