How are you going to remove or modify that line in a _safe_ and simple 
fashion when you'll have to?
Are you verifying if someone or something else has opened the 
/var/spool/cron/root file for editing while you're messing with it?

With a dedicated file (separate files for each task / purpose / 
application / whatever) in /etc/cron.d changes or an altogether removal 
are both trivial and safe.
