It's not in use in Fedora yet.

Yes. I have a patch ready to be sent to the mailing list to change
that to 127.0.1.1 (could be anything else really), as what we use in
Ubuntu.

It already is, you can enable or disable it via "dns=dnsmasq" in
/etc/NetworkManager/NetworkManager.conf; and since recently, you can
tweak the configuration using files in /etc/NetworkManager/dnsmasq.d.

See above; I think just the absolutely required parameters should be
on the command line, I think that's largely the case right now.

Depends if you run into those really obscure bugs. I think we've found
quite a few already, so things should be looking good for the most
part.
