Which leads me to the more general question of: enable CR on a production server, yes or no?
Not on production. Only for testing.
I'm not sure. Running production environments without CR enabled means you're running without current security updates for quite some time. Seems a bad and risky idea to me.
Like most things in the world, there is no single answer which will satisfy all the different demands that all the environments have. You have to weigh what each environment needs in terms of confidentiality, availability,
and
integrity (or whatever 3 or 4 letter acronym your site uses) then answer if it is a good idea or not. If you need high availability, then you are going to set things up where testing is done first then roll out of updates is done. If you need high confidentiality, you may push out security updates more and if you need high integrity, well you probably make the waterfall model look simple in what you have to do to make sure anything changes anywhere.
My reply was to the answer "Not on production. Only for testing.".
I didn't go into detail because I thought it's obvious that it's not so easy. I didn't mean to blindly feed all CR updates to production
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.
