No, if your website is protected by SSL there should be no option for plaintext.  None.

That's what we're already doing by allowing RC4 in DEFAULT settings.  It's a bad cipher.  Luckily we can rearrange ciphers to use betters ones before RC4.  The problem is servers who don't use HIGH or DEFAULT settings but rather cherry pick ciphers outside of their understanding and end up with bad choices.

This is being done upstream of Fedora.  Again, this is really a problem for server-side installations and less with client side installations.

It would be very interesting to see what servers are only supporting RC4 and ask them why they don't wish to use DEFAULT.
