Due to the setup of the modular daemon service files the reverting to non-socket activated daemons could have never worked. The reason is that masking the socket files prevents starting the daemons since they require (as in Requires= rather than Wants= in the service file) the sockets. On top of that it creates issues with some libvirt-guests setups and needlessly increases our support matrix. Nothing prevents users to modify their setup in a way that will still work without socket activation, but supporting such setup only creates burden on our part. This technically reverts most of commit 59d30adacd1d except the change made to the libvirtd manpage since the monolithic daemon still supports traditional mode of starting even on systemd.
