maybe you should just install CentOS inside a VM and test it

[root at srv-rhsoft:~]$ systemctl restart h
halt-local.service               haveged.service 
home.mount                       hostapd-guest.service 
httpd-lounge-worker.service      hybrid-sleep.target
halt.target                      hibernate.target 
hostapd-guest-interface.service  hostapd.service 
httpd.service

nobody but you installs systemd-units in /etc/ and so you have only one 
location AND customized ones - with sysvinit you had no way to override 
/etc/init.d/httpd without doing the work after each update again
