What's the aim here? Small size on disk? General fear of having
insecure but unused protocols linked with programs?
It's a shame it has to be packaged this way. I got half way through
writing a curl handler (which I really must finish) and my impression
is that at a code level they are quite modular, so maybe upstream
would be interested in turning them into real loadable modules. Then
we could package each protocol ("curl-http.so") as a separate RPM
which is really best of all worlds.
In the meantime I'd like to encourage every program in Fedora that
uses curl to call CURLOPT_PROTOCOLS(3). This is a real defence
against remote exploits (CVE-2013-0249 was one that happened in qemu).
