You do understand that if you ever have any problems you will be expected to provide logs, right? So no logs == no support?
AFAIK the startup log is a new and perhaps temporary measure to diagnose the hardening issues. It may be gone in a future release, otherwise I'm sure the feature will be tidied up.
p.s. The logs don't grow indefinitely, only the last four session logs are kept (only one of the startup logs), after that they are deleted automatically. Unless you are pathalogically short of disk space (in which case that would the real problem you should be addressing) then I encourage you to leave the logs alone.
