You think nobody could mess with 644 files that belong to you, but if another user has write permission to the same directory, then he can overwrite your files using vim and totally mess them up. I don't understand why this was chosen as the default behavior of vim. Seems dangerous.
When you do ":e yourfile | wq!" Vim is basically doing:
$ cat yourfile > myfile
$ rm yourfile
$ mv myfile yourfile
You're the one who gave others permission to mess with your filesystem.
