If you release a notice, large number of problems will by silently
marked as "skipped", since they have neither had their entries in
Release Notes, nor have been released as a separate errata. The problem
with bugs like that comes over and over again. I have reported two local
DoSes and none of them was a reason for releasing an errata. They were
(quite) serious:


Also problem with PECOFF handling resulted in local DoS, but I agree
it's not worth documenting, since it's not included by default. I
remember those problems were also serious and involved similar

(even applicable to RELENG_4):

There was a plan of updating security page to note, which type of
problems needs to be coordinated with security officer (local DoSes does
not) and which type of problems classifies for an errata. Is it still on
someone's TODO?
