Okay, fair enough. :)

/etc/vimrc has this:
"set backup " keep a backup file
So yep, no backups by default. As a test, I added a set backup line
to /root/.vimrc and edited /etc/fstab. A backup was created and the
context was retained. So score another one for vim (I checked and
didn't find evidence that restorecond stepped in to help). :)
But you are correct in noting that SELinux can cause problems if
programs do things to mess up the contexts. One example I have seen
is the vmware config script. It trashes the context of /etc/services
and sets off some denials when daemons try to access the file.
So far in F7 I haven't had many issues with SELinux. Those that did
come up I have been able to work out with the help of the tools that
are included. Things have come a long way since SELinux was first
enabled by default (in FC3, I think?).

As Mark Twain once said, "Few things are harder to put up with than a
good example." ;-)
