For example if you are doing autogenerated updates on config files you might want to test the config before restarting/reloading the daemon which is commonly done in enterprise environments running Freeradius and Bind atleast those environments I'm familiar with ( cups not so much )... Also the previous behaviour when starting a service used to throw out which config file and which line the syntac error occoured to the console however that's no longer the case see https://bugzilla.redhat.com/show_bug.cgi?id=684152. As I have mentioned to you previously systemd lacks certain administrative features ( yet ) like fine grained failour handling ( like ExecStartPreFail= etc. ) and more and it comes as a no surprice since you seem to have a limited sysadmin perspective/experience on things ( after all you are a developer not sysadmin ) as your blog post indicates which are targeted more at the above average end user running something @ home than real sysadmins in real enterprise environments from my pov.
