tcpwrap is legacy code, that is barely maintained upstream. It's APIs are awful, and the feature set it exposes (such as DNS and IDENT access control) questionnable. We should not support this natively in systemd. Hence, let's remove the code. If people want to continue making use of this, they can do so by plugging in "tcpd" for the processes they start. With that scheme things are as well or badly supported as they were from traditional inetd, hence no functionality is really lost.
