Because you intentionally disable it per client. Disabling memcache globally on heavy load server (e.g. mailserver) is like jumping from skyscraper without a parachute. (I know what I am talking about https://pagure.io/SSSD/sssd/issue/3520) Such misfeature should not have a place in upstream. We should not repeat the same mistake as with allowing authentication without tls. Ideal would be have this PR just as a downstream patch to make one particular customer (with unreasonable request due to workarounds on top of workarounds) happy.
