ExecStartPre= takes care of the startup check as in the usecase when the 
unit is not running and you initially configured the Apache daemon

Adding ExecStop= "before" actual ExecStop= line to stop the daemon takes 
care of preventing you from restarting you if you made configuration 
changes while the daemon/services was running should not continue with 
the stop process if the ExecStop command fails.

Anyway beside that point daemon,services that actual come with 
configuration file syntax checkers like apache does ( maybe in what 20 
or so range ) , are few and far between let alone those configuration 
syntax checker that actually exist out there fail properly if they do...
