Vulnerability F5

I think the security concerns of Aiyappa's are shared by many other people, including myself. I'd like to know if F5 has a timely plan of upgrading the default settings in accordance with new security findings, for many people do rely on the default settings to be secure. I myself would rather not customise the cipher settings of all my SSL profiles. As for RC4, is there any potential adverse effect if it is disabled, since this has not been disabled in the default settings by F5 for almost a year since the RC4 issue was identified?
