One thing I have learned in mailing lists is that it isn't always obvious
and there is rarely anything which meets common sense. I have dealt with
too many policies set at some site because the person read a comment on
email/reddit/stack-overflow and didn't see the obvious nature of something.
Instead they decided that the short nature was the MUST do and end up with
replicating things which the original poster did not expect.
Or sometimes happens someone does believe that it is as simple as they
stated and no matter what they turn on CR for every system (or turn off all
updates or whatever simple solution they expound as being the one true
solution.)
That said, I should have asked what you meant by that versus going for a
high-horse response on my own. I apologize.
