Agreed. So if the two clients cannot negotiate on AES128 or 3DES you would rather have them communicate without any encryption just because RC4 has been cracked? If you choose to allow AES128/3DES only that is your decision to make. We are talking about the default ciphers here and to teach the components to favour AES128/3DES over ARCFOUR. I see no harm in that.
