Comment 3 for bug 1851673

Per the guidance to ensure that charms are providing opinionated defaults - I don't believe it is crucial to enable customisation of the Ciphers, but we do need to ensure TLS1.0 and TLS1.1 are removed from the supported ciphers. It is now widely held that TLS1.0 and TLS1.1 are deprecated, and that we should be following industry practices: "Industry has actively followed guidance provided by NIST and the PCI Council to deprecate TLSv1.0 and TLSv1.1 by June 30, 2018. TLSv1.2 should remain a minimum baseline for TLS support at this time." [0]
